I would still trust a PhD in any field over some commercialized "artist". At least he went through the rigorous process of obtaining that degree. It changes people for the good, in my opinion.
In this noisy world that we find ourselves in today, one MUST cultivate critical thinking skills.
I don't trust phds because they "sound smart". Indeed, true smartness lies in simplifying complex concepts without much loss of information. I know the types of faux intellects you are referring to. Beware of them.
I trust phds more because my prior on their ability to use critical thinking is much higher than a Hollywood dimwit who is paid to express emotions in people.
It is still your job to trust, but verify. It is just easier to verify logically sound arguments or insights.
