People who are doing research that relates to human intelligence in some way should probably not follow this exact line of reasoning.

Those people depend upon funding that is contingent on public opinion of how valid their research is.

Also by making a research question disreputable, talented people might avoid it and those with ulterior motives might flock to it.

Currently the only people who dare to touch this field in any meaningful way are those who are already tenured, and while that is the whole purpose of tenure, the fact remains that even if these people are due to their age (as the topic wasn't always taboo) not really showing the negative effects of the above paragraph they are still old. And old brains just don't work that well when it comes to coming up with new stuff.

Deciding a piece of knowledge should be considered dangerous knowledge will necessarily lead to the deception of others and self on many different levels and in many different ways. I agree with the estimation made by some others that will produce Dragon in the garage dynamics which will induce many of the same bad results and biases you seem to wish to ameliorate.
