What causes your depression: serotonin or what you experience? The answer: the question is invalid! Both play a role, and are interconnected. You cannot say that one of these is the cause.
Why people don’t want antidepressants but do want psychotherapy
A lot of people think antidepressants are worthless. Is psychotherapy better than an antidepressant? There is no evidence for this. It seems to me that antidepressants suffer a disadvantage in our perception as compared to psychotherapy, in that their mechanism of action is quite invisible and not instinctively comprehensible.
Does dopamine make you happy, and is methylphenidate (Ritalin) addictive?

The girl with half a brain
The girl without the right hemisphere of her brain functions pretty normally. How is this possible?
The placebo effect doesn’t exist
Depression lifts with placebo pills, joint pain disappears after a placebo operation. Changes in the brain can be observed after the use of a placebo. How do such effects of sham treatment come about? Placebos do have effects. But THE placebo effect does not exist.
Autism is hereditary, but you don’t inherit autism
The probability of having autism is greater for an individual if it runs in their family. This suggests hereditary factors. But what do you actually inherit? What you inherit is a predisposition for a specific development of your brain. This, together with what you experience while growing up, can lead to the development of a mild to severe form of autism.

Instead, we carry a preexisting image of our surroundings in our head, and we check if that matches with our perceptions. Sometimes this goes awry.
