I wrote up some thoughts about cognitive and ethical illusions — ways our evolved perceptual and mental processes fail us. I wrote, in part:
[T]he spirit of recent ethical philosophy… seems to want to defer all of the ethical action until all of the loose ends have been tied up in ethical theory.
Which is a shame, because it seems to me that this would be an especially fruitful time to develop a practical discipline of ethics. While some of the great human weaknesses and temptations have been known and discussed for ages, we have never had such precise investigation of ethical blind spots and illusions as we have today.
The science of manipulating people by identifying and then exploiting these conceptual flaws (which crop up not only in optical and ethical illusions, but in all sorts of assessments of what is really going on around us and what is in our best interests) has been running far ahead of any efforts to teach people any sort of self-defense. I don’t see why we shouldn’t start trying to catch up.
