Psychological diagnoses can help us understand the people around us - but it comes at a cost. It takes minutes to diagnose yourself with a psychological disorder (or even fictional characters) online. For example, the term narcissist is often associated with Donald Trump, and Lady Macbeth could be said to have OCD due to her constant hand-washing. Labelling people into pre-existing categories could benefit them by increasing awareness and providing them with a ticket to access support. However, as Lucy Foulkes discusses, labels have a power which could exacerbate rather than reduce the stigma.
