In response to Mere Messiahs

I'd say the same applies to Catholics' aggrandisement of the Virgin Mary. Catholics are supposed to try to emulate someone whose virtue was so great before she was even conceived that she was born free from original sin (something no-one else can claim according to the appaling original sin doctrine). She then receives messages from god, bears his child (becoming both virgin and mother, a combination of virtuous states no-one else can achieve) and is bodily claimed into heaven. Isn't a human being who actually struggles with temptation, someone who overcomes actual weaknesses and flaws a better and more useful role model and example than this super-powered, divine intervention-fuelled juggernaut of unmatchable virtue? What can those seeking how to be good learn from someone to whom the mere notion of being bad is completely alien?

Sounds good, I'll look forward to it.

Thanks for the feedback. I think you're right that a key omission here is failing to note that each step must be useful in itself, and provide a non-negligable boost to chances of survival on its own. It also implies a greater sense of purpose than exists in nature (there's no mind aiming for things, just more resilient creatures surviving).

I realise the model has many flaws and omits wider context such as competition, but I'm still tempted by the appeal of using such a common situation as the analogy. Talk of guessing passwords or rolling dice does make excellent analogies, but if you want to engage someone it helps to talk about something closer to their personal experience, and I imagine most people played hangman on a board or margin at some point at school.

On a similar subject, the boardgame Guess Who is a perfect illustration of the point in Burdensome Details. Each additional claim about Person X (do they wear glasses? are they blond?) leads you to knock down some possibilities.

Hangman as analogy for Natural Selection

0 Delta 05 October 2012 12:02PM

Hi guys,

I was trying to come up with a helpful analogy to help explain natural selection in simple terms and it occurred to me that the game Hangman might make a useful analogy, albeit an imperfect and simplified one. I'd be interested to hear your thoughts on this and any other useful analogies or strategies for explaining in simple terms how natural selection allows complexity to arise from simplicity and how it is distinct from random chance.

The Hangman analogy I propose would read as follows:

A long word is chosen, say with a dozen letters, and a dozen blanks are drawn on the paper. Person A then guesses a letter. If the letter is present in the word a blank is filled in and the player can try another letter and so on. Their further guesses will be informed by the letters they have already discovered rather than being completely random. If the letter is not present the player loses a life (represented by the drawing of part of the gallows). If they run out of lives the game is over and a new player, Person B takes their place. Person B must start from the beginning.

In this analogy the long word is a complex adaption, requiring many seperate chance mutations to build it. Each guessed letter is a chance mutation that can be beneficial (correct answers bring you closer) or detrimental (wrong ones cost you lives). The loss of all lives represents the extinction of the species, meaning no further mutations can occur. Person B is an entirely different species that can't "compare notes" with Person A and hence must start from the beginning (though they may take a different route).

The benefit of this analogy is it's an example of random guesses still having a sense of forward progression (discovered letters are not removed, and gradually build up), and that it refers to a simple game I think most people will be familiar with. You could then go on to explain how a complex adaption takes many more than a dozen steps, that there are many more than 24 possible mutations, and that each guess takes many generations, to give a sense of the timescales involved.

The weaknesses are considerable and include the inability to go backwards (beneficial changes can be lost as well as gained) and the existence of a single specific end goal (the unknown word), rather than this being a continual process without set targets. It also ignores the possibility that a beneficial mutation does not spread throughout the species.

I very much doubt this is an original suggestion, but it seemed a handy simplification of the "password-guessing" analogy I was just reading about in Dawkins' "The Blind Watchmaker". Any comments or alternative methods would be welcome (I'm still not very widely read on the subject of evolution so I'm sure others have put it more clearly than I could).

Thanks for your time.

Very interesting article, and a real "ouch" moment for me when I realised that all my escapism growing up had exactly this effect. By becoming engaged with fictional worlds through films, books and games you can start to disengage with the world, finding nothing so interesting and vibrant in it (this is a particular risk if you are young and haven't found activities and people you value in reality yet). The scary thing was when I was realised the characters in my books felt more real than people in reality. If you have trouble connecting with people books offer ready-made connections that can distract you from getting the social skills you need to form meaningful relationships in real life.

To an extent I think I am still prey to this, so does anyone have advice on ways to balance your escapist pleasures so you can still enjoy them without losing the vibrancy of real life?

I realise it is over a year later but can I ask how it went, or whether anyone has advice for someone in a similar position? I felt similar existential terror when reading The Selfish Gene and realising on one level I'm just a machine that will someday break down, leaving nothing behind. How do you respond to something like that? I get that you need to strike a balance between being sufficiently aware of your fragility and mortality to drive yourself to do things that matter (ideally supporting measures that will reduce said human fragility) but not so much you obsess over it and become depressed, but it can seem a pretty tricky balance to strike, especially if you are temperamentally inclined towards obsessiveness, negativity and akrasia.

Cameron just made a homeopathy advocate Health Secretary. Maybe the problem was Britain not being broken enough...

Hmm, maybe I shouldn't have said "always" given that acting ability is required to signal a belief you don't hold, but I do think what I suggest is the ideal. I think someone who trained themselves to do what I suggest, by studying people skills and so forth, would do better as they'd get the social benefits of conformity and without the disadvantages of false beliefs clouding predictions (though admittedly the time investment of learning these skills would have to be considered).

Short version: I think this is possible with training and would make you "win" more often, and thus it's what a rationalist would do (unless the cost of training proved prohibitive, of which I'm doubtful since these skills are very transferable).

I'm not sure what you meant by the magisteria remark, but I get the impression that advocating spiritual/long-term beliefs to less stringent standards than short term ones isn't generally seen as a good thing (see Eliezer's "Outside the Laboratory" post among others).

Really enjoyed the article, and thanks for the link to the nerds article. I think it is easy to underestimate how big an effect this has. When growing up my mother was always incredibly helpful with schoolwork, but because she focussed on the negative, stating mistakes directly rather than praising the good first and then carefully broaching the subject, she came across as very harsh and demanding. Despite the best possible motives her delivery made me less happy and made me more resistent to suggestions and mutinous.

Unfortunately I think I've fallen into the same trap (I wrote a comment on my sister's blog which rather upset her because I didn't follow the advice here) so thanks for flagging this and pointing me to some reading material.
