Yes, Anders_H is Doctor of Science in Epidemiology. He's someone worth listening to when he tells you about what can and can't be done with experiment design.


Oooh, an appeal to authority. If that is the case he is no doubt highly accomplished. However, that need not translate to blind deference.

This is a text conversation, so rhetorical questions aren't immediately apparent. Moreover, we're in a community that explicitly celebrates reason over other modes of rhetoric. So, my interpretation of his question about counterfactual conditions was interpreted was sincere rather than disingenuous.

Another month, another rationality quotes thread. The rules are:

  • Provide sufficient information (URL, title, date, page number, etc.) to enable a reader to find the place where you read the quote, or its original source if available. Do not quote with only a name.
  • Please post all quotes separately, so that they can be upvoted or downvoted separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
  • Do not quote yourself.
  • Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
  • No more than 5 quotes per person per monthly thread, please.
