Is the psychology lecture a pyramid scheme?

Generally speaking, psychology lectures are not pyramid schemes.

Because it is mainly to impart knowledge.

Or promote their studio.

Not pulling my head

The lecture must be substantive.

Something useful.

But there are some lectures that you should learn to distinguish.

I want to see if the lecturer has integrity and morality.

Don't tell some false lies.

Psychology is deep, so we should pay attention to it.
