Compare to people who have the means to build, modify, and test the systems they talk about. Maybe no one can be this kind of an expert in the field of sociology. But if that’s the case do not present yourself as confident. Answer most questions with “I don’t know”. Refuse praise. Exude humility.
Short of it: 30-ish year career as a psychology professor and researcher focused on morality and emotions. If you follow the track of his popular science books, The Anxious Generation (on smartphone use in teens) is very much a sequel to The Coddling of the American Mind, which itself is something of a sequel to The Righteous Mind, and so on. There's a very clear linearity and progression to his works.
At I said this might just be a field where normal expectations of expertise can’t be met. But that doesn’t mean you can rescale and match the confidence of other fields.

I'm fairly cynical about touch screen devices and kids, and won't be letting mine near any until they're old enough (whenever that is) but haidt's own charts don't support his conclusions in that book.
The actual reason teen mental health diagnoses started increasing so much?? An obamacare-related screening and reporting requirement change for pediatrics.
