Until recently, there was an equestrian component to Modern Pentathlon
at the Olympics. Now with dressage, say, the rider will spend all their working time of years developing a relationship with their horse. In Modern Pentathlon, as a nod to times when soldiers has to ride unfamiliar horses, the competitor gets something like 20 minutes to get to know their horse before having to ride it showjumping.

It's like that for a hospital psychiatrist in an acute ward, where basically they say (again and again), "Here's Bob, whom you've never met before. You've got 30 minutes with them to figure out what's wrong and prescribe a solution."

With a system that works that way, we expect magic from them, when the don't deliver the magic we demand, we blame them in various ways. And when people insist that the psychiatrist in an acute ward knows what they're doing, they often do so inadvertently ascribing an unrealistic amount of magic power to the medically qualified.

The trouble with mental health is that brains, minds, and people in general are very complex beings. There is an astronomical number of ways things can go wrong in someone's mind or brain. To expect a medical professional to be able to pin things down accurately in the space of a few 30 minute consultations is akin to magical thinking.
