What clearly can be useful is to create a list of models and ideas we’ve already assimilated that haven’t been really tested or are based on research that still awaits replication.
I like the idea and agree this could be useful, but our first focus should be on reproducing well-established results to make sure that Less Wrong has the ability to so. Afterward, if we succeed, then it makes sense to proceed cautiously to replicating weak results or testing new hypotheses. Otherwise, if we don’t succeed in reproducing well-established results, then we lack the ability to investigate more speculative ideas.
We face numerous additional burdens over experimentalists in academia, two of which stand out to me: (1) a currently unknown sampling bias and response rate, and (2) a general inability to blind our Less Wrong subjects to the hypotheses and predictions of our experiments.
It may be instructive to take a look at some of the recent papers on online psychometric assessment in personality psychology. They have worked on establishing the effects of online assessment (as opposed to traditional paper-and-pencil or face-to-face assessments) and proposed guidelines for doing experiments online:
