Thanks! I’ll check them out after the long weekend.
Last night I posted an example “social experiment” in the General Discussion forum. Anyone interested in playing with the threats-to-validity framework might try using it to pick apart that study and design a better one.
If I were more ambitious, I might offer a prize for the best study—but then I’d have to judge the entries , obtain a prize, etc. So for now I’m counting on intrinsic motivation or sheer boredom to push folks into taking a whack at this collective study-design exercise.
I can’t find your exercize in the General Discussion Forum.
