I guess I need to chase the scientific article myself.

As the other reader says, the point of studies is to develop objective truth.

After one generation, this new objective truth starts getting ingrained in people’s minds. That’s usually because after one generation the people who held old beliefs are out of the scene and new young people who believe in obvious things come to be part of the scene.

That’s how society changes over time. Not people changing their minds, but new people with a different way of seeing the same things.
