This was so informative! I think it can be hard, especially with women, because ultimately these tells are for people who FEEL guilty. That can be deceiving for those who routinely feel or are made to feel guilty when they haven't actually done something morally wrong.
On the other side, psychopaths probably aren't going to have these specific tells because they DON'T feel guilt in a typical way.
One of the things this kind of insightful article helps me with may surprise people - as someone with ADHD and a requisite lack of self-feelings-awareness, they help me to read my own emotions and act in accordance!
