Being able to analyze your thought patterns outside your own head could lead to all sorts of improvements. You could find which teaching techniques are actually the most effective. You could objectively find when you are most and least focused. You could pinpoint when anxious thoughts began and their trigger. And best of all, you could do this personally, with a partner, or in a group based on your choice.
Also you can give someone an FMRI as a brain scanning polygraph today. But there are still a ton of questions about it’s legitimacy.
