Any of those things really does provide Bayesian evidence the relevant groups will have lower status in a community.
Sure does. Then again, the WSJ is a complete right-wing garbage politically, but is quite good at economics, so it's not so that unusual to get some tidbits of wisdom from unsavory sources.
If avoiding offense or increasing participation of a group is a very high priority
I would not expect this forum to bend over backwards to avoid accidentally offending people. The rule of thumb for an online discussion is "do not offend and do not be easily offended".
I wouldn't say positions become necessarily "irrational" across a wide range.
Right, where to set the boundary is a personal preference and not an issue of rationality. Expecting others to move their boundary upon your request might be.
Summary: Current social psychology research is probably on average compromised by political bias leftward. Conservative researchers are likely discriminated against in at least this field. More importantly papers and research that does not fit a liberal perspective faces greater barriers and burdens.
An article in the online publication inside higher ed on a survey on anti-conservative bias among social psychologists.
The link above is worth following. The problems that arise remind me of the situation with academic and our own ethics in light of this paper.
I can't help but think that self-assessments are probably too generous. For predictive power of how an individual behaves when the behaviour in question is undesirable, I'm more likely to take their estimate of how "colleagues" behave than their estimate of how they personally do.
This shouldn't be surprising to hear since to quote CharlieSheen: "we even have LW posters who have in academia personally experienced discrimination and harassment because of their right wing politics."
While I can see Lammers' point that this as disturbing from a fairness perspective to people grinding their way through academia and should serve as warning for right wing LessWrong readers working through the system, I find the issue of how this our heavy reliance on academia for our map of reality might lead to us inheriting such distortions of the map of reality much more concerning. Overall in light of this if a widely accepted conclusion from social psychology favours a "right wing" perspective it is more likely to be correct than if no such biases against such perspectives existed. Conclusions that favour "left wing" perspective are also somewhat less likely to be true than if no such biases existed. We should update accordingly.
I also think there are reasons to think we may have similar problems on this site.
