Let BBC Radio Surrey & Sussex know that you support its sensible stance on so-called homeopathy experts

BBC Radio Surrey and Sussex broadcast a programme with a lunchtime expert slot. In the past, this slot has included a homeopath offering medical advice to callers.When I heard about this, I was shocked and contacted the programme’s producer. I was delighted that Sara David, the station manager, responded firmly: “We will not be giving advice based on homeopathy on BBC Sussex and BBC Surrey in the future.

The homeopathic community is unhappy about my complaint and the BBC’s sensible response. One homeopathic website has now started a campaign to lobby the BBC to change its position. The site encourages people to write to the BBC, complain to MPs and contact the press.

To balance and hopefully overwhelm the homeopathy campaign, I think it is important that the BBC realises that there are lots of people opposed to pseudoscience and who support BBC Radio Surrey & Sussex’s decision not to promote pseudoscientists as experts.

Rather than bombarding the BBC with emails and letters, please scroll to the bottom of this page and leave a comment. I will forward the list of comments to the station manager at the end of the week.

If you want to read more about what happaned, then you can read an account of my original complaint to the BBC here and you can visit the homeopathy campaign page opposed to my complaint here.

Why I am mildly perturbed by Lab in a Lorry

Good to see lots of comments after my blog “ Why I hate Lab in a Lorry & the Einstein Ballet“.

Perhaps I should start by making two further points.

1. My main criticism is with funders, not with those who actually conduct the projects. Lab in a Lorry might be conducted with enthusiasm and skill by highly motivated and knowledgeable people (including volunteers), but if the running costs of the project are astronomical then it remains a poor project. The problem resides not with those running the project on the ground, but those who commissioned it and who continue to fund it from on high. Similarly, I am not blaming sponsors, who are trying to support science with hard cash or resources. I am blaming those who spend that money and use those resources. As I have said before, I might be wrong, in which case I am keen to see the analysis, formal or informal.

2. There are good science engagement projects. Richard Wiseman’s videos cost virtually nothing, yet they are witty and thought-provoking. Take a look at Top Ten Quirky Science Tricks for Parties, which has over 5 million hits. Or listen to the Pod Delusion, which reaches 10,000 people every week. The audience includes many non-scientists, because of the podcast’s mix of content. It’s run on a shoestring budget and would probably benefit from some support. I helped start the Undergraduate Ambassadors Scheme, a credited undergraduate degree module that currently operates in over 100 departments around the UK and which sends over 1,000 undergraduates into schools each year. At the moment, as far as I know, it runs on about £5,000 per year. It does require lecturers to devote time to it, but they are involved because the module helps them achieve an important goal, namely graduates with transferable skills. I am also closely involved in the Enigma Project, which takes my Enigma to schools in order to explore maths and its links with history, technology and, of course, codes. It ran over 100 events last year, half of which were full day workshops, and it reached 12,000 students … and it operates at a profit, including the loan fee for the Enigma. I am also impressed with the various activities at the maths and computing departments at Queen Mary, University of London. Anything involving Matt Parker seems to be priceless, yet relatively cheap. Maths Inspirations is also worth a mention. It lacks anything innovative, flashy or stylish, but it delivers inspiring maths lectures to students in large numbers. It mimics the sixth form study day format, which is known to be profitable and appreciated by teachers, but it makes the format more affordable and transportable, so that the lectures range from Kent to Durham. It baffles me why learned institutions have not jumped on this idea and created Physics Inspirations or Chemistry Inspirations or Science Inspirations.

I am still hoping for a response from the people behind Lab in a Lorry or the Institute of Physics. I would be delighted to receive a robust defence of the project, which showed that is actually excellent value for money. I am often grumpy and critical, but I prefer being happy and impressed.

In the meantime, here is my best effort at addressing as many as possible of the existing comments on the blog in 30 minutes.
(Apologies in advance for typos, errors, omissions, etc. I am trying to answer every point quickly and briefly, rather than provide a long, structured response to one particular point.)

Rolandjackson (Chief Executive of the British Science Association)

You criticise my use of the word ‘hate’.

Happy to change it. I have put in a holding phrase. Let me know the most appropriate word or phrase and I will update it.

The word was partly put there to generate interest, and it was partly put there because it is not far from how I feel.

Physics education in the UK is in a terrible state (is the word ‘terrible’ ok? Probably not. Sorry) and it makes me sad and angry when I think money is being wasted when it could be spent on trying to fix the problem.

You raise the problem of metrics

I agree that it is hard to measure the impact of a project and even to assess its real cost. However, if the goal is clear (e.g., improve take up of A level by A and A* GCSE students or increase positive attitudes towards science among parents), then it should be possible to assess projects.

In particular, if £1 million (fair guess?) has been spent on Lab in a Lorry, then the organisers ought to be able to give some idea of the impact, particularly if it is being run year after year after year.

I have sat in meetings where we have discussed the assessment of Lab in a Lorry and other engagement projects, and my recollection is that the level of scrutiny is poor. There seems to be an understanding that nobody is allowed to say anything too critical, because after all people are doing their best.

If absolute measurement is hard, then organisations should at least be able to rank their projects in relative terms, so that top projects can be expanded and bottom projects abandoned or revamped.

One approach would be to have an independent panel assess science engagement projects. Experienced and successful science communicators have a good nose for what works and what does not. This is far from ideal, but I think it would filter out the worst projects sooner rather than later.

By the way, I don’t think I am arguing just that some projects are a bit below par, but rather that some projects are far below par, inasmuch as they are hugely expensive and not having nearly the proportionate impact.

You support innovation

So do I. My point is that I often see innovation for innovation’s sake. Let’s make it interactive. Let’s give the audience buttons to press. Let’s do it through mime. Let’s present it in Esperanto. Let’s turn it into a ballet.

You enjoyed the Einstein Ballet and say it should be judged in comparison with Swan Lake, not as a piece of science education

It was commissioned by the Institute of Physics. I don’t know how much was required in terms of IoP money or sponsorship, but I am arguing that the money could have been better spent. Perhaps I am wrong. Ultimately it is up to the members of the IoP to judge if their money is being well spent. Lots of people are bored by physics and lots of people are bored by ballet, so IMHO this project merely allowed people to be bored more efficiently.

(Apologies to ballet lovers. Ballet has no meaning for me, but I realise many others (more cultured than me) do appreciate it. Ballet has its place and I am not saying that we should cut funding to ballet or the arts. However, IMHO physicists should not be spending its money on ballet projects. BTW I also don’t recommend that the Ballet Rambert commits funding to the Isis muon and neutron source at the Rutherford Appleton Laboratory.)

Nigelbrown & David McGloin & Andy Lloyd

You seem to support Lab in a Lorry in the Highlands

Maybe Lab in a Lorry is cost-effective in that area of the UK. I certainly would not want the money to be spent elsewhere. I just think the money could be spent more effectively and efficiently, even in the Highlands.

David M Pyle

You support Time Truck in Cambridge

I am sure that it achieves great things, but could those great things be achieved in cheaper ways? Perhaps the project could then be run twice a year. How about trying to work out the full cost of the project?

Sarah Martin

You say “expensive and not cost-effective” are the same thing.

No. Sorry if it was not clear. I don’t mind if projects are expensive as long as they have a huge positive impact, which then makes the projects cost-effective.

You say “Comparing them on cost and attendance alone is simplistic”

I agree. WRT Lab in a Lorry I mentioned “any wider impact”. Impact is not just numbers of people, but the difference made per person. Wider impact could include, for example, positive local press that might influence parents to be more supportive of science. I agree with the approach suggested by @amyplatypus at Wellcome: “We also look at the type and depth of engagement, whether we reached people we wouldn’t otherwise…”

David McGloin & Suzie Sheehy

You point out the good things that result from Lab in a Lorry (eg hands on experience for pupils & science communication experience for undergraduates)

As with Time Truck, I am sure that it achieves great things, but could those great things be achieved in cheaper ways? Lab in a suitcase?

Andy Lloyd

You suggest Skeptics in the Pub is not real science engagement

Having spoken at maybe 20 pubs, I think one third of the audience is made up of non-scientists, eg. partners, friends, curious folk. But it would be interesting to do a survey. Perhaps all the pubs could pick a month (October?) and ask how many people in the audience have a degree in science or engineering or maths?

In any case, it does not really matter. Skeptics in the Pub does not take money from anyone, so it can do whatever it wants.

My concern is with projects funded by research councils or other public bodies. There is a limited (but not insignificant) pot of money for UK science engagement, and I am asking if it is being well spent.

Jensen Warwick

You say assessment is hard

Fair point and I talk a bit about this in response to Roland Jackson. However, the problem starts even before assessment. I sometimes wonder how some of these projects get funded in the first place.

Andrew Holding

You ask for help running Cambridge Skeptics in the Pub.

Someone help, please.

The Pizza Express Summits

I published a blog on 15 July, 2012: Two Questions for Monty Don About Organic Farming.

If you visit the blog, then you will see that the 15th comment is a response from Monty Don. I have also pasted it below.

Unfortunately, he has chosen to ignore all of my points and questions. If I was a member of the Soil Association, then I think I would be disappointed that my President decided not to engage in discussion. Instead, he suggests that I am incapable of understanding the issues surrounding organic farming because I am not “temperamentally and intellectually suited”.

I have heard similar comments from homeopaths, who feel that I am not qualified to write about or criticise homeopathy. Indeed, homeopaths and organic farmers seem to have lot in common. Remember, the Soil Association supports homeopathy and many organic dairies use homeopathy.

So, where do we go from here? Well, here is my invitation to Monty.

Monty, I am disappointed by your lack of a serious response to my blog. This dialogue was initiated by you. You tweeted me, not vice versa. You tweeted and accused me of being “pathetic”, “mischievous, ridiculous, truly unhelpful”, “plain silly” and “silly” again. I offered to talk on the phone, as yet no response. I wrote a blog in order have a more mature discussion, but you have not addressed any of the points that I have raised.

I am still keen and willing to discuss organic farming with you. In the spirit of positive dialogue, please let me take you out to dinner one evening in West or Central London. By all means bring along a friendly expert and I will also ask an expert to join us, so you will have a chance to engage with someone who is both critical of and knowledgeable about organic farming. If possible, Wednesday evening’s are best, as we can then make the most of the Pizza Express Orange Wednesday offer. The rules are simple:

1. We all turn up with an open mind.
2. We all argue our points, discuss the issues and ask/answer questions.
3. We all leave as friends.
4. I will pick up the bill (dough balls and desserts included)

You can contact me via to arrange a date.

If the first dinner goes well, then we could continue with homeopathy and then GM as separate dinner topics. Or, if you want to change the order, we could start with homeopathy or GM.

Monty Don responded on 17 July, 2012:

It is helping no one by reducing this to itemised point-scoring. Surely the idea is to understand what is happening rather than prove things right or wrong? Suggest you inform yourself a lot more before taking this any further. If you are genuinely interested in understanding what it is all about start by reading Michael Pollan, Colin Tudge and Rob Hopkins. No specific scientific work so you may not feel comfortable with it but very good cross section of the field.

Importantly it is not a contest or case of anything being right or wrong. It is all about everyone concerned joining thoughts, practices and concepts to nurturing and sustaining all forms of life – and humans not least – as successfully as possible. That begs a thousand questions rather than trying to pick holes in one or two issues.

If that looks as though I am dodging your questions then so be it – and in a way I am because they are not sensible out of the context of the much bigger picture and I hate the idea of point scoring on something as important as this.

Having known you for nigh on 20 years – albeit with great gaps – I suspect that you are as temperamentally and intellectually suited to immersing yourself in organic, holistic agriculture as I am in particle physics. Your mind just doesnt work that way. That does not make you wrong or me right. Well,OK, I am just being polite but it doesn’t make you bad for being wrong…

with very best wishes

Two questions for Monty Don about organic farming

Normal 0 false false false MicrosoftInternetExplorer4

I should start by stressing that organic farming is not an area of particular interest. I only have a superficial understanding and knowledge of the subject, but I think it is clear that:

  1. In relation to fruit and veg, one of the main reasons for the growth in the market for organic products is that the public believes the produce is healthier, safer and more nutritious. However, according to the Food Standards Agency (2009) and the Research Institute of Organic Agriculture in Switzerland (2009), the overall balance of evidence does not support this view. Personally, I suspect that organic food is less healthy. I probably prefer the risk of pesticides traces rather the risk of bacteria traces, but let’s just assume that the price premium on organic does not buy any health/safety bonus.

  2. Another reason for the growth in the organic fruit and veg market is that the public believes that organic is good for the environment, and that the UK would be a better place if crop production shifted from modern intensive farming to organic.

I will return to point (2) later and challenge it, but, first, this is what happened a couple of days ago to trigger this blog.

On Wednesday 11 July, @mark_lynas tweeted about a proposition in California (funded by Big Quacka) to demand labelling of genetically engineered foods. I shared the view that this was just an attempt to scaremonger, as there is no significant risk associated with such products according to the Royal Society of Medicine (2008). Also, the US National Academies of Sciences (2004), stated: “To date, no adverse health effects attributed to genetic engineering have been documented in the human population.”

Mark Lynas, who is an environmentalist activist who takes a scientific and balanced view, went on to tweet: “It’s unnecessary. Organic lobby trying to get a skull and crossbones on competitors’ produce.”

Then Mark Lynas tweeted: “How about a label on organic foods: ‘Warning, land-inefficient product, may cause damage to the environment’”

This tweet challenges point (2), which I stated earlier, which is that organic farmers claim their way of growing crops is better for the environment. Mark’s counterargument is that organic must be bad for the environment if crops require, let’s say, 25% more land to generate the same yield.

Unfortunately Mark’s tweet and my retweeting upset Monty Don, President of the Soil Association. Monty tweeted in response:

@TheMontyDon come on Simon, you can do better than that. That is just pathetic.

That struck me as somewhat harsh and rather lacking in a sense of humour, so I tried to engage with Monty. We worked together on “Tomorrow’s World” back in 1994/1995 and even went on a filming trip to Australia, and I know he is a decent chap. Here is the twitter exchange that followed.

@TheMontyDon come on Simon, you can do better than that.
That is just pathetic.

@SLSingh Hello Monty, good to hear from you. What exactly are you objecting too? Very happy to chat on the phone if that is easier.

@TheMontyDon Objecting to mischeivous, ridiculous, truly unhelpful remark Simon. Adds nothing to any debate. And I know you as a very bloke.

@SLSingh Which tweet? I had a busy tweeting day today. genuinely keen to understand your concern.

@TheMontyDon the one about labelling organic products ‘land inefficient’ Simon. Just plain silly.

@SLSingh Semi-joke but based on evidence  “overall, organic yields are significantly lower than conventional yields”

@TheMontyDon yields in relationship to inputs? to health? to ecology? to diversity? No. Picking at a corner of this subject is silly

The exchange was a bit more complicated than the slightly edited version above, but these are the main and interesting points.

In short, Monty (supported by some tweets from @suebeesley) was arguing that the yield per acre point in isolation is not significant, and that it is only possible to discuss organic farming in a holistic manner. For example, @suebeesley seemed to argue that organic crops may require more land to generate the same yield, but this did not matter in the bigger pictures because: “So, once you add in the land ‘cost’ of externalities for non-organic, and reduce meat consumption in organic, the gap is bridged?”

So part of the organic argument seems to be that we should eat less meat to free up land currently occupied by cows in order to be able to grow more organic crops. This would mean that we could feed ourselves organically without having to turn more of the countryside into farmland.

That’s a fair point, but it relies on a major change in eating habits. A start would be for the organic movement to stop selling meat, but I think many supporters of organic are not vegetarians.

In any case, even if we all eat less meat, then I would argue that we should continue with intensive farming of crops and that any land that is recouped from cows, sheep, pigs and chickens could be used for more intensive farming for export or GM biofuel crops or wind turbines or house-building or returned to nature. Basically, I would argue that the land could be used for anything except inefficient organic crops.

I accept that the argument is more complicated than I could convey in a handful of tweets, but I think that my core point (copied from Mark Lynas) is still valid, which is that the public do not realise that if we were to increase our consumption of organic crops, then it would mean turning more of the countryside into fields.

I think it is fair to say that we could say goodbye to between 5% and 10% of the countryside if we were to hand over crop production to the organic industry.

In conclusion, I don’t think my tweet was “pathetic”, “mischievous, ridiculous, truly unhelpful”, “plain silly” and “silly” again,

Finally, Monty, can I ask you two questions?

  1. Do you agree with the conclusions of the meta-analysis in Nature (2012), which reviewed 66 studies comparing the yields of 34 different crop species, and which concluded that the yield per acre for organic farming is 3% less for fruit, 11% less for legumes, 26% less for cereals and 33% less for vegetables. So, while organic fruit production is fairly efficient, everything else performs poorly to very poorly. By all means say that there are other factors to be considered when considering organic farming, but was this a good piece of research on the issue of yield per acre? If not, why not?
  1. While I have the ear of the President of the Soil, Monty, what is all the nonsense about supporting homeopathy for farm animals? Really? No, seriously, really? Chris Atkinson, your Head of Standards, wrote in 2011: “Encouraging healthy farm animals can be supported by using complementary therapies – which include homeopathy – where these can be shown to be effective.” Please tell me the conditions for which homeopathy is appropriate and the evidence that means it has been “shown to be effective”.

You can leave a comment of any length below. By all means add additional detail, but please answer the questions above in (1) and (2).

My polite complaint to the BBC & its impact

Last Thursday, @callyauckland tweeted:


Penny Edwards, from Helios #TunWells today on

@BBCSurrey #homeopathy 1pm, until about 1.45pm.


I think the tweet was from one of Penny’s fans and was intended to promote her and her radio appearance. This was RT’ed by @lecanardnoir, which is when I spotted it.


I decided to investigate further. My correspondence over the next 24 hours illustrates exactly why skeptics/rationalists/scientists need to complain when it is clear that the media is promoting potentially dangerous pseudoscience. This is particularly true in the case of the BBC, which has a responsibility to maintain the standards expected of a public service broadcaster.


First, before the homeopath appeared on air, I rang the producer and asked why a homeopath was appearing on the programme. Was there a newsworthy peg? No. She explained that the homeopath appeared regularly in the 1pm expert slot of the Joe Talbot show on BBC Radio Surrey and BBC Radio Sussex. I explained why this was problematic, but the producer seemed confused. Her three main responses were:

     (a) Penny knows what she is talking about. After all, she has a busy surgery.
     (b) Penny has a website and is allowed to advertise, so she must be ok.
     (c) Nobody had ever complained before.


My responses were:
     (a) There are busy psychic hotlines, but they are also very dodgy.

      (b) The Advertising Standards Authority is currently dealing with over 150 complaints about homeopathic websites.

      (c) I said I would send out a quick tweet to see if others shared my view.


     Does homeopath deserve expert

slot on@BBCSurrey  today at 1pm? Is this the BBC at its best? Yes/No? 


There were 17 twitter replies in the next 5 minutes, all sharing my concern. I accept that my twitter followers are not a fair cross-section of the British public, but the replies proved that I was not a lone voice/ear.


Later that day, I listened to the show on i-Player. It was a painful experience. It was half an hour of utter tosh, concentrated baloney and dodgy advice, interspersed with some easy listening tunes. It was a major piece of promotion for homeopaths. At least, that’s my opinion. You can hear it for yourself here:


The URL should take you to the start of Penny’s contribution at 1hr 9m 48s.


Prompted by callers and emails, Penny talked about homeopathy in relation to gout, multiple sclerosis, high blood pressure, Raynaud’s syndrome, psoriasis, urinary tract infection and back pain following a miscarriage.


At this point, I should stress that Penny Edwards seems to have a genuine belief that homeopathy is effective. Sadly, she is wrong. She is merely doling out placebo sugar pills to her patients.


Given the producer’s lack of interest in my concerns and the presenter’s apparent enthusiasm for homeopathy, I thought I would complain straight to the station’s managing editor/director, Sara David.


Ms David replied within eleven minutes and said she would get back to me after her meetings. The following day she wrote:


Thank you for your email about yesterday’s phone-in with Penny Edwards.  I have reviewed the programme and spoken to its producer, and made clear that this was the wrong kind of guest, and the wrong kind of advice, for a phone-in programme on BBC Sussex and BBC Surrey.   We will not be giving advice based on homeopathy on BBC Sussex and BBC Surrey in the future.


I must admit that I was a bit shocked. No half-hearted defence. No tedious back and forth. No attempt at a cover up. Just a simple: “We got it wrong. It won’t happen again.”


We all make mistakes. As my teacher used to say, “That’s why they put rubbers on the end of pencils.”


So what can we conclusions can we draw from this?


  1. Nobody had previously complained, which is why this had been allowed to continue. So, the only way to stop pseudoscience in the media is to raise concerns (firmly, but politely).


  1. Sometimes an informal complaint or a friendly note to the presenter, producer or managing editor is enough. If you receive a sensible response then great. If not, then a formal complaint to the BBC Trust or OFCOM might be necessary.


  1. Sara David’s response is very important, as I think it sets a benchmark that other local radio stations now have to match. If you hear a homeopath or any other quack on your local radio station, then please send the station a friendly note. You might even cite Ms David’s response. If that does not work, then submit a formal complaint.


Finally, as someone who is campaigning for more free speech (, am I being a hypocrite? I think there is no contradiction. If the BBC promotes a homeopath as a health expert, without any critical voice to counter the twaddle, then this is anti-scientific, pseudoscientific and possibly dangerous. Libel reform is about encouraging debate and criticism, it is not about the BBC providing a free platform for deluded quacks to promote potentially dangerous treatments. Of course, homeopathy is harmless, but if patients choose it over conventional remedies, then the issue of patient safety is very real.


Ps. Although I love the BBC and worked in the BBC Science Department for five years, complaining to the BBC holds a special place in my heart. One of my first adventures in skepticism was when I complained about a programme that gave a misleading impression of the power of acupuncture. You can find more information about the complaint here.


PPs. Well done to @JonMcA who actually submitted a formal complaint about this to the BBC. May not be necessary now, but it might still be interesting to see if the BBC Trust is as unequivocal in its apology as Sara David.

Why did Psychic Sally lose her powers in September 2011?

Yesterday, Psychic Sally (aka Sally Morgan) announced that she is suing the Daily Mail for libel. She is taking action against two articles published in the Daily Mail last year in the wake of allegations made in September that Sally uses an earpiece to receive information on stage in order to help her perform apparent acts of mediumship. Sally Morgan has strongly denied these allegations.


You can find out more about the allegations and subsequent controversy in an article by Chris French, and in some blogs by me here, here, here, here and here.


With September’s earpiecegate in mind, I went to see Psychic Sally in three shows late last year. Before discussing the content of the shows, I should point out that Psychic Sally was not wearing an earpiece when I saw her. On each occasion her hair was tucked behind her ears. She has admitted to wearing an earpiece in the past (for stage direction only), but even this was not being used when I attended her shows.


I found her performances to be very disappointing. Apart from the ethical issues and some distasteful readings (in my opinion), she had very few direct hits and spent much of the evenings struggling to give convincing readings (in my opinion).


Her national tour has been a major success with 1,000-seat venues sold out night after night (tickets £20- £25), so I wondered why she was so popular in light of the lacklustre performances that I had witnessed.. Perhaps her current popularity was based on previous success. Maybe her performances had been more impressive earlier in the year. How could I find out if the shows that I had seen were a pale shadow of the sort of mediumship Sally had been capable of in the past?


Fortunately, Ticketmaster allows people to post reviews of Sally’s shows (and other shows) on its website. Reviewers can also award up to five stars. So, yesterday morning I looked at all of the reviews for 2011 and worked out the average star rating for each month. Before I reveal the data, I should point out a couple of things.


  1. This was a rush job, so it does need to be checked. I have tried to be accurate, but there were lots  of shows and reviews to wade through.
  2. There are some gaps in the data. This might be because Sally was on holiday and there were no shows, or because shows not sold via Ticketmaster are not reviewed on its site.

This is what I found:


January            81 reviews        4.5 stars

February          85                    4.6

March            130                    4.3

April                11                    4.2

May                  7                    4.6

June                29                    4.4

July                  –                       –

August             –                        –          

Sept                12                    2.3

October           90                    2.5

November       100                    2.9

December        –                       –


Technically, I probably should not present this data in a bar chart, but I have already drawn it and this is what the data set looks like. As you can see, fans were much less impressed by her shows at the end of the year. I have shown September as a half-width bar, as all the reviewed shows in September took place in the second half of the month, after the allegations about the earpiece.


So why bother with this exercise? First, those thinking about going to see Sally might be interested to know that she is much less popular than she used to be in terms of her reviews. Second, does it throw any light on Sally’s supposed psychic powers?


There are many reasons why Sally’s performances might have suffered from autumn onwards. For example,


  1. Sally might have been nervous and anxious after the allegations.
  2. Critics might have posted fake negative reviews in late 2011 – perhaps encouraged by the publicity.
  3. Sally’s powers may have genuinely waned and may continue to wane. Maybe she has lost the knack.


Perhaps you can think of other reasons why Sally’s performance suffered from September onwards.

Can you think of a name for my new thing?

My New Year’s resolution is to set up a small hub for pursuing and promoting various skeptical activities. In fact, planning is going well and I hope to announce something in late January. However, I still don’t have a name for this entity, so I need your help to find one.

I don’t want to constrain your creativity, but here are some thoughts that might be helpful…

1. This is undoubtedly a skeptical ‘thing’ that is being created, but the word skeptic has pros and cons.

2. The ‘thing’ will act as an umbrella for various projects, so it needs a name that is not too specific.

3. The ‘thing’ will probably have a charitable status, so it could have “Foundation” stuck at the front or end or nowhere.

4. The ‘thing’ will probably interact with grown-ups, so a name that carries some credibility would be preferable.

5. On the other hand, quirkiness is also a good thing.

In short, all suggestions would be welcome.

Please email me your suggestion via

Whoever comes up with the winning name will get something nice.
