Are you conducting some kind of experiment, or planning to? Well, I don't know about it yet! So when the stunning results come out, I can say "hey, maybe you just got lucky. If your experiment had returned a negative result then we wouldn't have heard anything about it".
This is called publication bias.
So I'm launching the anti publication bias registry, a place to record EA-related experiments before you know what the results are going to be.
It's on a wiki, which allows you to change the description afterwards - this has good points and bad points. A good point is that it allows you to change your experimental design as you go along, in order to best fit the world. A bad point is that this can introduce bias. But remember, we do have the edit history so blatant cheating will be hard (such as completely changing an experiment, or deleting it). More subtle cheating is also discouraged, such as adding extra statistical tests because the data seem to be pointing that way.
You can also register experiments by commenting on this post - someone will probably copy it to the wiki eventually anyway.
Be as detailed as you can be bothered to be in your experiment descriptions. This will hopefully encourage others to follow your example and be careful in how they set up their experiments.
A second purpose of this is to introduce social commitment towards actually completing and writing up experiments once they've been suggested.
Have fun doing science!
