I obviously believe there's a value in having control groups Not only is that obvious but it is actually conveyed by my comment. It is a required premise for the assertion of altruism to make sense.
Not so, there exists altruism that is worthless or even of negative value. An all-altrustic CooperateBot is what allows DefectBots to thrive. Someone can altruistically spend all his time praying to imaginary deities for the salvation of mankind, and his prayers would still be useless. To think that altruism is about value is a map-territory confusion.
My comment observes that sacrificing one's own (expected) health for the furthering of human knowledge is an act of altruism.
Your comment doesn't just say it's altruistic. It also tells him that if he doesn't feel like being an altruist, that he should tell people that "placebos are for pussies". Perhaps you were just joking when you effectively told him to insult altruists, and I didn't get it.
Either way, if he defected in this manner, not just he'd be partially sabotaging the experiment he signed up for, he'd probably be sabotaging his future chances of being accepted in any other trial. I know that if I was a doctor, I would be less likely to accept you in a medical trial.
Your comment actively and directly sabotages human knowledge for your own political ends.
Um, what? I don't understand. What deceit do you believe I committed in my above comment?
Let me see if I can summarize this thread:
Wedrifid made a strategic observation that if a person cares more about their own health then the integrity of the trial it makes sense to find out whether they are on placebo and, if they are, leave the trial and seek other solutions. He did this with somewhat characteristic colorful language.
You then voted him down for expressing values you disagree with. This is a use of downvoting that a lot of people here frown on, myself included (though I don't downvote people for explaining their reasons for downvoting, ev...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
If continuing the discussion becomes impractical, that means you win at open threads; a celebratory top-level post on the topic is traditional.
