A few examples (in approximately increasing order of controversy):
If you proceed anyway...
- Identify knowledge that may be dangerous. Forewarned is forearmed.
- Try to cut dangerous knowledge out of your decision network. Don’t let it influence other beliefs or your actions without your conscious awareness. You can’t succeed completely at this, but it might help.
- Deliberately lower dangerous priors, by acknowledging the possibility that your brain is contaminating your reasoning and then overcompensating, because you know that you’re still too overconfident.
- Spend a disproportionate amount of time seeking contradictory evidence. If believing something could have a great cost to your values, make a commensurately great effort to be right.
- Just don’t do it. It’s not worth it. And if I found out, I’d have to figure out where you live, track you down, and kill you.
Downvotes have caused me to put a lot of effort into changing the tone of my communications on Less Wrong so that they are no longer significantly less agreeable (nice) than the group average.
In the early 1990s the newsgroups about computers and other technical subjects were similar to Less Wrong: mostly male, mean IQ above 130, vastly denser in libertarians than the population of any country, the best place online for people already high in rationality to improve their rationality.
Aside from differences in the "shape" of the conversation caused by differences in the "mediating" software used to implement the conversation, the biggest difference between the technical newsgroups of the early 1990s and Less Wrong is that the tone of Less Wrong is much more agreeable.
For example, there was much less evidence IIRC of a desire to spare someone's feelings on the technical newsgroups of the early 1990s, and flames (impassioned harangues of a length almost never seen in comments here and of a level of vitriol very rare here) were very common -- but then again the mediating software probably pulled for deep nesting of replies more than Less Wrong's software does, and most of those flames occured in very deeply nested flamewars with only 2 or 3 participants.
Having seen both types of tone, which do you think is more effective in improving rationality and sharing ideas?
