indeed, there are instances of simialr things in psychology versus parapsychology- in 'straight' psychology it is usual i!
n their
statistics that a 0.05 significance is accepted as 'proof' (they tend not to use the contentius P word though!) - in short, that expirimental treatments or experimental conditions, such as whether the higher does of caffeine in an attention experiemnt results in faster reaction speed, that kind fo thing- are found to be supported if it can be demonstrated by the stats that their effects have a less than 1 in 20 likelihood of simply happenign by chance, which is what the .05 means
in parapsychology it is common to go to 0.005 or further in order to demonstrate signficances, a magnitude of ten higher, and an area that 'straight' psychology rarely extends itself to, as it makes the maths simply horrendous (or more horrendous than it already is)

is an excellent journal paper on this from the nineties, but all my psych gear is in boxes, so i can't give the ref right now, sorry
- Wow, that's quite a difference in statistical analysis. I had no idea. Thanks for the info, Dave.
