i have been working up some new material around the pattern basis of human intelligence. As a part of that I collected some of the common effects that are know to prevent objectivity in humans. At the moment I have these and thought I would share them:
Now those are known, and summarised in more detail in Thiele’s 2006 book The Heart of Judgement which is proving an enjoyable read. There are of course a lot more. What I find fascinating is that while the community as a whole knows of these errors they assume that the solution is to exhort or train people not to make them. In practice all of these are a consequence of the pattern basis and activation patterns through which we filter data. It follows from this that training people not to do the above will either not work or will only partially succeed which is more dangerous.
The other approach is to recognise that these are simply the downsides of what is otherwise a powerful evolutionary advantage of humans. If that is the case then we need to work with the effects above, not attempt idealistically to assume we can prevent them. The trainer who knows about the above, but then says they can train people not to exhibit those effects is themselves the victim of at least two!
More on this tomorrow.
