I interpret that as referring to one's justification for making claims of more-than-base-rate-likelihood-for-weird-off-the-wall-suggestions - especially if you're going to take up a lot of people's time based on anecdotes, you should at least be presenting decent anecdotes.
If you dismissed or didn't bring up anecdotes, I imagine there'd also be a positive response. For example, if one argued for using bright lights like thus, I imagine it'd go over well: 'I found studies X Y and Z where bright lights increased alertness over a day; applying the usual meta-analytical considerations, I guesstimate there's a 20% chance it'll work on ordinary people for a payoff of $Z; and on Amazon these lights cost $A and to run for a year uses $B in eletricity; and turns out, 0.20 * Z > $A+$B. Also I have a rubbishy personal anecdote: after doing this calculation, I tried out the lights and it seems to be working.'
(My own opinion is that lights are stupid easy to test so there's no excuse for not doing a self-experiment. Flip a coin each morning to turn the light on or keep it off, and write down which & how much you think you got done at the end of the day! But if you can't do that, at least trying to get past the honeymoon period is a start.)
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
