There is a law which states that you can’t discriminate according to religious beliefs. In principle I think this is a bad law, because the idea that someone can’t be refused employment on the basis that they’re delusional is absurd, but pragmatically I think it’s necessary. Relatively few people choose their religious beliefs and people whose parents have inducted them into cults have it bad enough without having a tough time getting a job.

The pragmatic necessity, though, doesn’t extend to any old nonsense. This week, there have been two weird uses of this law. The first was Tim Nicholson, who won a judgement about unfair dismissal after he was sacked for hectoring his company about green issues.

His solicitor, Shah Qureshi, said: “Essentially what the judgment says is that a belief in man-made climate change and the alleged resulting moral imperative is capable of being a philosophical belief and is therefore protected by the 2003 religion or belief regulations.”

This was best summed up, I think, by David Mitchell on the News Quiz, who essentially said that it’s good these ideas get respect but that it’s bad that the way they do so is to be more like religions. He said that arbitrary religious reckonings musn’t be questioned but scientific facts backed by evidence are fair game and that that was the wrong way around.

More recently,

Alan Power, a trainer with Greater Manchester Police, will rely on a previous judgment that found his belief in mediums who contact the dead is akin to a religious or philosophical conviction. In an unpublished judgement in Mr Power’s favour seen by The Independent, the employment specialist Judge Peter Russell said that psychic beliefs are capable of being religious beliefs for the purpose of the Employment Equality (Religion or Belief) Regulations 2003.

If you need convincing that this is perverse, read this:

Judge Peter Russell… said: “I am satisfied that the claimant’s beliefs that there is life after death and that the dead can be contacted through mediums are worthy of respect in a democratic society”

Really? I would say they’re worthy of mockery, and I’d further say that they’re a very good reason to sack him if

Mr Power told the court that he had a belief in psychics and their “usefulness in police investigations”.

According to a blog,

The judge said that a later hearing would have to establish whether Power was ‘dismissed for the possession of religious or philosophical beliefs or for his alleged inappropriate foisting of his beliefs on others’.

But then, according to the Times,

Mr Power, who worked for Greater Manchester Police for three weeks in October last year, was sacked over his work with neighbouring police forces and his “current work in the psychic field”, the tribunal heard.

If Power wins the second hearing then this would effectively shepherdus into the fictional world of Rob Grant’s Incompetence. This is a book set in a dystopian future in which it is illegal to discriminate on the grounds of incompetence, and therefore everyone does the job they want and most of them are terrible at it.

This is part of the wider problem of religion: it demands that we respect ideas that range from slightly odd to downright idiotic, but doesn’t properly define which ones, so any attempt to mandate that respect is doomed. You can’t build an internally consistent set of rules if you have to accommodate the mandatory respect of a handful of strange beliefs. You end up having to respect any belief regardless of its merit and that leads to people being killed by elevators with buttons wired up for floors that don’t exist.

It should be illegal to fire someone because they believe in man-made climate change because that’s sensible. It should be legal to fire someone because they believe in psychic mediums because that’s stupid. Surely we have a law for that? Surely that’s what the ‘unfair dismissal’ means?

Presumably if you’re reading this you’ve heard that Alan Johnson demanded David Nutt resign as head of something called the Advisory Council on the Misuse of Drugs for comments he made in a speech reproduced as a pamphlet you can download. I have read his speech. It’s quite interesting. It discusses the intentions of the drug classification system, criticises the current implementation, and offers a proposal for and justification of an alternative based on a systematic comparison the effects of a range of drugs, according to criteria decided by the public. This is complete with references, and in short exactly the sort of thing a Professor of Neuropsychopharmacology should be doing and while it’s not perfect I honestly can’t imagine why anyone would sack him for it.

Ann Widdecombe, who can always be relied upon to jump into the wrong side of any issue put before her, offered this dismal attempt at an explanation:

Look, you read your newspapers every day. Scientific advice changes almost as often as the wind.

You can hear this on iPlayer now; I heard about it from @krypto. And she’s right, of course, because the sum total of everything we know about the universe changes when we learn new things. Your choices are to go with what we know now, understanding that it could change in the future, or to make shit up and run with that. If you want to make shit up then fine (it’s called religion), but don’t foist your made up shit on me, and don’t employ a scientific advisor to make it look credible or else exactly this is bound to happen.

The Daily Mail’s A N Wilson also defended Johnson, who presumably wishes he wouldn’t, saying

The only difference between Hitler and previous governments was that he believed, with babyish credulity, in science as the only truth. He allowed scientists freedoms which a civilised government would have checked.

This was accompanied by an inset photo of Hitler until The Jan Moir Police made them take it down.

While obviously Wilson’s biggest crime against reason in that quote is kidnapping the word ‘only’ and dumping it, lost and confused, in front of an idea well outside its comfort zone, he’s also quaintly ignorant. Hitler was a big fan of science in principle, but corrupted it with quackery and racist ideology, and all but banned theoretical work as ‘Jewish science’ (except secretly where it might help his war effort). Anyone caught doing science that didn’t fit the racist message was fired. One mathematician even attempted to prove quantum mechanics and Nazism were the same thing. All of this is covered in John Grant’s Corrupted Science which I presume the Daily Mail’s A N Wilson hasn’t read, because it is a book.

Melanie Phillips, also of the Mail, implied pretty strongly that Nutt’s claims were simply wrong, which would at least be a legitimate defence of his sacking, were it true.

The reason they are casting the Home Secretary as the villain of this episode is that the chattering classes have bought into the idea that soft drugs are indeed less dangerous than alcohol or tobacco. They therefore think Nutt is the voice of scientific reason.

But he is not.

She does, at least, appear to have read his speech, as she criticises it piece by context-free piece, which is perhaps as strong an endorsement as a scientific claim can get. Melanie Phillips’ views on science are almost uniformly opposed to reality. Take, for example her butchering of the Cochrane report on MMR or her support for ‘intelligent design’. Incidentally, Nutt’s speech cites the MMR fiasco as an example of harm done by ignoring evidence. Phillips doesn’t mention this. (For a better cricism of Nutt’s ideas, see the Transform blog post about the original paper.)

On what I will generously refer to as ‘the left’, Alan Johnson himself defended his actions by saying

Professor Nutt was not sacked for his views, which I respect but disagree with … He was asked to go because he cannot be both a government adviser and a campaigner against government policy. This principle is well understood and long established.

Widdecombe also made this case. And it’s true, although irrelevant. This was a lecture about scientific work, not a campaign. In any case, I think it’s equally well understood and established that you can’t ignore science and expect your science adviser to sit there and let you get on with it. Even if Nutt had crossed the line into campaigning, I think he would have been justified in doing so. As it is, Nutt did little more than present an alternative idea for consideration and present arguments in its favour (i.e., science). Gordon Brown believes Nutt should be fired for this, “because we cannot send mixed messages”, an argument pre-emptively demolished by Nutt himself on page 12 of the PDF transcript.

Martin at LayScience.net points out [with my annotation in square brackets] that

nobody hearing Professor Nutt speaking about the government is going to confuse him with a Labour minister [and it was made clear Nutt was speaking only as a scientist], so the problem that Gordon Brown is referring to is the problem of a senior scientist publishing and publicising research that contradicts the government line. In Gordon Brown’s world of control freakery, such dissent is not to be tolerated.

which sounds familiar but I shan’t comment on why because I’m not sure what happens if both sides of an argument are compared to Hitler.

Don’t listen to these people, and don’t listen to me. Read Nutt’s speech for yourself. If you’re a scientist, you’ll find its structure and tone familiar and start to wonder what all the fuss was about. If not, just read it and then ask yourself if you’d consider it ‘campaigning against government policy’ or ‘a man telling a class what he does at work’.

So Facebook has a new feature.

On the right hand side, it’s long since had little faces, with names, and the phrase ‘you have one mutual friend’. Which is fine when it’s that guy from uni who I never got round to adding but less useful when it’s a passing acquaintance of someone I randomly met at a pub after Facebook friending briefly became the new swapping numbers. And that’s passably useful, I guess, although there do seem to be only about six people going round and round in that slot like they’re terrifyingly stalking me and they have no idea.

Underneath that is the new feature. This is a someone on my friends list I’ve presumably not contacted in a while (or, I haven’t messaged on Facebook because I genuinely know them). It has their name and face, then says ‘catch up with him’ and ‘write on his wall’. The only use I can possibly think for this is that it will keep reminding me of which of my lesser-seen friends’ names connects to which human face. That’s a useful service, like flashcards for babies learning to speak, and naturally it’s only trying to help (and by ‘help’ obviously I mean, ‘ensure I do as much of my communication as possible via Facebook and not only read their ads but force my friends to read their ads’). I just feel like any day now Facebook is going to pop up a picture of an ex with a link saying ‘what happened to that nice girl you were seeing?’.

Well, thanks, Facebook. You’re helping a lot.

Obviously fundamentalist religion bothers me. It makes me very angry to see anyone try to enforce rules based on ideas that are unproven, much less false. But I’ve never really known what to think of the more mainstream, moderate everyday religion.

I mean, I don’t like it in principle because I think if people are going to believe something then it should be true. (And for the record, anyone who falls for Mormonism or Scientology is a fully levelled-up imbecile, with a million inexperience points and the Shield of Ignorance card.) I also object to the relativist attitude the current culture promotes. Lastly, I object to anyone identifying themselves as ‘Catholic’ because that’s an endorsement of Pope Batshit-Mental XVI, and more generally a large number of believers gives any religion’s lunatic fringe a dangerous illusion of credibility. And these are all fine objections in principle, but in practice, in reality, for the purposes of day-to-day thinking, I just find it weird.

I think I’ve essentially been an atheist ever since it occurred to me to think about religion. For years since then I’ve surrounded myself with young, middle-class, liberal science students and their ilk, so now when I meet someone I assume they’re an atheist in the same way I assume they like cake: so completely have I accepted that there aren’t any gods that it simply wouldn’t occur to me that anyone might disagree. I mean, I know religious people exist outside of churches and other countries and the Internet, but only in the same way that I know a lot of people are conservatives and I know the weekend isn’t an infinite time-bank in which I can catch up with any ridiculous amount of work I care to ignore during the week: I can remember that these things are true but they’re kind of not programmed into my internal model of the world. You know, like general relativity.

But then… there are a couple of my friends who are theists, and every so often I see a Facebook update or something* that casually mentions God or Jesus or Allah vel cetera as if it’s a real person and it just weirds me out. For one thing, I don’t know what to do when I’m invited to thank God for some meaningless turn of fortune. Anything honest seems impolite. How is that fair? They’re the one with the delusion — if anyone’s going to be in an impossible situation, surely it should be them?

In the end I just ignore them. I know if I correct them they won’t listen anyway. Although that said, I do the same thing in pub quizzes and I’ve lost out on a prize that way, so maybe I need to be more assertive. In the meantime, though, my sheepishness to correct the deluded stands me in good stead for handling the religious. Sometimes I post passive-aggressively atheist messages just to balance it out.

The feeling that it’s weird persists, though. Here, I think (in that implicit, subconscious way we do most of our low-level thinking) is a list of updates, from people I care about, to let me know what’s going on in their lives… and here’s one that also involves a fictional character that my friend genuinely believes to be real. I literally don’t know how to process that information. It’s like presenting DOS with the command “c:\make me a cup of tea”. My face just goes blank while my brain throws it the neural equivalent of an unhandled exception error and emails a crash report to Charles Darwin.

I don’t really have a point to make here about anyone other than myself. (I thought I’d wait until the end to mention that. So you’d read it.) I think I just needed to write this somewhere before it drove me crazy. I vaguely hope that any religious folk who happen across this post might understand a bit better what it’s like to be an atheist, although I suspect they might only learn what it’s like to be a socially inept geek-atheist who is procrastinating rather than write his thesis.


*It’s always online. I assume this is either because there’s less taboo about being religious on the internet or because people rapidly learn not to invoke their imaginary friend in my company.

The conversation I just had

October 12th, 2009

Me: Hello?

Steve: [in a thick, perhaps German, accent] Hello. I’m Steve, and I’m calling from Save My Bill. Okay?

Me: Okaaay…

[pause]

Steve: Is that okay?

Me: Yes.

[pause]

Steve: What’s okay?

And then I hung up.

My PhD research makes use of CT scanning, so I’ve had to do a lot of research into that for the literature review. Here is some of the knowledge I’ve gained:

The mathematical framework that makes CT possible was all outlined in 1917 by Johann Radon. Then in the 50s, the mathematical framework was outlined again, differently, by Allan McLeod Cormack, who invented the CT scanner without having read Radon’s work. Then, in 1973, the CT scanner was invented by Godfrey Hounsfield, who hadn’t read Radon or Cormack’s work. For this, Cormack and Hounsfield won the Nobel Prize.

I’ll be honest, this somewhat undermines the importance of the literature review in my mind.

Only… I wonder what amazing stuff we’d have invented by now if we’d started inventing information technologies instead of pissing about with steam engines all that time. There should have been Discworld-style semaphore towers up and down the country in Tudor times at least. Why should a message take days to get across the country just because that’s how long paper takes? We could have had a CT scanner in the 30s, for a start. By now I’m totally convinced we’d have flying cars and moonbases.

And even given that, scientific knowledge is still trapped in PDF versions of paper journals, behind a myriad different paywalls and arbitrary institutional subscription lists. That’s a terrible system. It should be on a big database, searchable by any parameter you like. If I’ve got a question to which mankind has found an answer, I should be able to run a quick-and-dirty search and get a good idea what that answer is in about fifteen minutes.

If you want jetpacks, don’t invent the jetpack, reform scientific information handling. Because that way it’ll come with teleports and moving hologram projectors and sexy androids and other implausible future stuff.

Apparently, the ‘relics’ (or ‘bits’) of St Thérèse de Lisieux are coming to town, which should at least prove marginally more lively and relevant than anything the Pope has to say on his forthcoming tour. Thérèse is a relatively modern saint, canonised apparently after someone reckoned a visit to her grave restored their sight, so I would hope these are genuine remains from that grave rather than just some joke shop bit of bone approved by the Grand High Catholic Board Of Reality who have so far authenticated three of John the Baptist’s heads.

My question is this: is the following quote from St Thérèse the sort of thing you would want to publicise if it was your religion?

Be not afraid to tell Jesus that you love Him; even though it be without feeling, this is the way to oblige Him to help you, and carry you like a little child too feeble to walk.

Read it again, this time mentally substituting ‘your boyfriend’ for ‘Jesus’. I think that’s a little bit like something Jo Brand might say.

I was going to throw this up on Google Reader and let FriendFeed tweet it at you all, but since I have apparently become the standard reference for ‘perfect formula’ stories, I thought I’d stick it up on here. Presenting… The Respectable Face Of PR Science Formulae!

From the b3ta newsletter, it’s OK Cupid’s analysis of what words and phrases are more successful than others at eliciting a response to a first-contact message. Essentially, it’s a formula for the perfect on-line chat-up line, and it basically reads ’spell right, don’t be a creep, and mention specific interests’. It’s just a blog post, so it’s still not really Proper, Peer-Reviewed Science, but there are enough mentions of N and f and statistical significance — all used quite correctly — as well as a note about anonymisation, that my instinct says they probably did it right. And the results are a nice mix of the obvious (read the other person’s profile), the counter-intuitive (confidence is bad) and the interesting (mentioning a religion is good but mentioning atheism is better).

In any case, it does what the original ‘perfect formulae’ story tried to do (or at least what its creator claims he tried to do and I see no reason to disbelieve him), which is to combine clever PR with an actual attempt to show how science can be relevant. And it worked, because here it is in the Telegraph, alongside a photo of attractive young people kissing each other, for purely illustrative reasons, naturally. Wouldn’t it be nice if companies realised they could get the PR without the sneers of intellectuals if they just did these things right?

Also I’m inclined to like it because it seems to say that self-effacing male atheist physicists are sexy. And I think we can all agree that that’s basically indisputable.
