I can respect an individual's right to cognitive integrity, but I also agree that resulting actions and even the quality of one's judgment are consequently open to critique.

Excluded middle: deciding to investigate further (to minimize unintended consequences) before engaging is also an action.

I'm also wary of hidden biases in moral intuitions. This researcher captures my concerns in a nutshell:

A runaway trolley is hurtling down the tracks toward five people who will be killed if it proceeds on its present course. You can save these five people by diverting the trolley onto a different set of tracks, one that has only one person on it, but if you do this that person will be killed. Is it morally permissible to turn the trolley and thus prevent five deaths at the cost of one? Most people say yes. Now consider a slightly different dilemma. Once again, the trolley is headed for five people. You are on a footbridge over the tracks next to a large man. The only way to save the five people is to push this man off the bridge and into the path of the trolley. Is that morally permissible? Most people say no.
These two cases create a puzzle for moral philosophers: What makes it okay to sacrifice one person for the sake of five others in the first case but not in the second case? But there is also a psychological puzzle here: How does everyone know (or "know") that it's okay to turn the trolley but not okay to push the man off the bridge? My collaborators and I have collected brain imaging data suggesting that emotional responses are an important part of the answer...

As everyone knows, we humans are beset by a number of serious social problems: war, terrorism, the destruction of the environment, etc. Most people think that the cure for these ills is a heaping helping of common sense morality: "If only people everywhere would do what they know, deep down, is right, we'd all get along."
I believe that the opposite is true, that the aforementioned problems are a product of well-intentioned people abiding by their respective common senses, and that the only long-run solution to these problems is for people to develop a healthy distrust of moral common sense. This is largely because our social instincts were not designed for the modern world. Nor, for that matter, were they designed to promote peace and happiness in the world for which they were designed, the world of our hunter-gatherer ancestors.
