I got the same color as you by the way.

@anothercrappypianist: That’s the reason why the 3% number is considered so significant in Daryl Bem’s study. His study was very large and involved over a thousand people. As for why the “ESP effect” is only 3%, I would suggest that the reason may be because not everybody is gifted in that department. The 3% effect is the measure of ESP in those who are gifted when combined and averaged with the general population (which includes those who are not-so-gifted).

@anothercrappypianist: However, an observable mathematic effect says that the more randomly generated numbers you add to the mix, statistically, the less variance there will be. It would not be surprising for the average of 10 randomly generated numbers between 0 and 10 to come out to something like 7, but it would be utterly shocking if the average of 1,000,000,000 randomly generated numbers between 0 and 10 was not almost exactly 5.

anothercrappypianist: Say you have a random number generator that randomly generates a number between 0 and 10. The average of 0 and 10 is 5, but if you take the average of small amount of randomly generated numbers, it will not always be 5. You'll get some high readings and some low readings. That variance of average is to be expected with a small sample size.

It was different

@anothercrappypianist If ESP is expected to result in absurd margins like you're asking for, we wouldn't be arguing about it. lol

3% above chance is really an underwhelming effect size. Such a small difference could easily be accounted for by a very minor methodological flaw. I'll start getting excited when we start seeing 20-30% effect sizes from experiments with rigorous methodologies that can be reliably repeated by unrelated researchers.
BTW, I picked blue. It's my favourite colour. :)

@anothercrappypianist lol - i like the fact that despite your reservations on the methodolgy - you still played along :)
I also realise that something like colour (which i chose for my micro-experiment) is so easily subjective - with people having strong favourites for colours and football teams etc.
So anyway... what we've established is i'm no scientist!
Thanks for the comment ;)
