Presumably, they're taught similar curriculums at school and, read similar books, so it doesn't really surprise me that they say the same sort of things. They're surely taught to do their job a certain way. There may even be penalties if they stray too far off script.
This is one of my peeves about education in general. There is too much time and effort spent on trying to shape "how" people think as if people don't think correctly. I mean, sure, one could have a disease or be neuro-divergent or any number of reasons why they might think differently whether or not you could describe it as "wrong" thinking... but people are inherently thinkers.
Babies have to learn a lot of things very quickly in life. Language of those around them without any meaningful cues, they have to interpret their surroundings and figure out that people are communicating and decipher how that works. Meanwhile, they are learning how to operate their own physical bodies to do things like walking even as they are growing and often their legs are not the same length. You literally cannot stop a child from learning up until they are around school age... then everything changes, and suddenly we start trying to force kids to think in certain ways, ways that "experts" have decided is the way to think... and then we break so many kids who become broken adults.
And, I'm not even talking about religious indoctrination or political indoctrination or all of those nefarious things we impose on people... I'm talking more subtle things that adults try and impose on kids who already clearly have a super-efficient way of learning and adapting that has served them very well to that point.
Trying to tell people how to think is just wrong and leads to wrong places. People inherently know how to think. We are natural puzzle solvers.
We should instead focus on teaching verifiable repeatable things... teach knowledge and allow people to think how they think and absorb that knowledge and think new things as a result of that. This is how new ideas and new uses and unique configurations come about... people thinking naturally about things that other people have known for generations and suddenly seeing something different. That doesn't come from trying to force people to think a certain way. In fact, forcing people to think a certain way is a surefire method to ensure no one ever thinks of anything new ever again because if we all draw the same conclusions then we will never draw new ones.
I was always frustrated in school by teachers who wanted to teach a process and not a concept. Students would learn a process and never the concept and unless you gave them the EXACT scenario, they could not interpolate and figure out how to apply the concept to a previously unanticipated situation. The worst example of this I'll share below.
In college there was a time when a friend wanted to study for a Physics final. I didn't need to study myself, but I figured maybe I could help him. Colleges sell old exams so you can get an idea of the kind of questions that might be on a test to help you prepare. This friend had an old exam so we went through it, problem by problem and he seemed to get what was going on and felt good when we had finished studying.
After the exam a few days later, I saw him and he said to me, "Hey, that final was easy. They had all the same questions as were on that practice exam!" I responded, "Yeah, I was surprised to see those same questions, but they just changed units like Newtons to kg or vice-versa but otherwise used the same questions." My friend had a look when I said that... all the blood rushed from his face and he said, "They changed units?"
See... he just recognized the words and the numbers from the example problems so he picked the same answers. He spectacularly failed the exam because every answer he chose was wrong as a result. He did no critical thinking, no problem solving, he never learned the concepts... he only learned to work specific problems and if you changed them even slightly they meant nothing to him.
I knew someone else in high school... he would make 100% on the tests but there is always overlap in school where the next lesson builds on the previous one... so the next day after a test he had aced, he wouldn't know basic things. In this case, the teacher wasn't doing a good job of testing conceptual understanding so this student was able to study for the test and pass without actually understanding how to apply the concepts.
And bringing this full circle... the psychiatrist or psychologist all too often only knows to run through their checklist and shove you into whatever box the checklist says you should be shoved and put you on whatever therapy/drug the checklist says. Very few doctors seem to be good at critical thinking. Sure, they learn new checklists as new information gets rolled into the community... they learn to regurgitate the new buzzwords and treatments and diagnoses... but they don't really understand anything they are saying.
