Does that colleague really dislike you, or are you just imagining it? Most of us have wondered whether someone secretly dislikes us, but it can be difficult to tell because people rarely say so directly. Instead, psychologists suggest that social rejection can reveal itself through subtle behavioural cues, from reduced eye contact and particular body language to fleeting microexpressions of contempt.

There’s the hyperfocus, the creativity and the ability to perform under pressure. And then there’s the impulsiveness, the racing thoughts and the emotional dysregulation.
