Here's what my chemistry PhD friend said: "I’m constantly saddened by the propensity we have to label any behavioural characteristic deemed outside the “norm”. Also happens in many other spheres of medicine too. It allows parents to try and justify children’s behaviour by using a label rather than diligent parenting. Also allows the individual not to take accountability for their actions because I’m “insert a label”. Inevitably, medication is then justified to treat “insert a label” preventing the slower but natural “growing into themselves”."
