Not everyone, and not all the time. But many people, and often enough that it's a stereotype. So I think it's worth considering, particularly when you're looking at a customer base who (by and large) really aren't used to being condescended to.
Even if you and I personally aren't offended in the slightest by what OP said on sales calls, it's possible a psychologist in the fourth decade of her career might take "Are you sure that's right?" differently than we would.
His approach was never going to work, as doctors do not spend their time evaluating drugs in the way that he imagined.
It may have been a great product like you and others have said, he hasn't the faintest idea what physicians actually do day-to-day. He had apparently spent $40k over nearly a year before he talked to the first physician.
This biz was clearly made for consumers but yea ads are tough - need a lot of eyeballs.
The argument that “patients won’t know the difference so I can just do whatever” must break down at some point (hopefully before malpractice) but I think an argument of “I’ll just keep doing what I did before, it’s worked fine so far” doesn’t encourage worsening treatment or paying for more experimentation.
Edit to add: if you think a practitioner putting their own revenue/profits above providing quality care, then something's wrong with you.
So I'm not sure why you would expect a psychiatrist to do something she's not trained to do to (maybe) increase an already acceptable metric some arbitrarily small amount higher.
The position that doctors should be trying new things to improve their care sounds good but in practice most doctors are strongly biased towards the status quo and usually inaction is preferred to a slightly unknown action, even if that action has better expectancy.
