Whether you call it brainwashing, indoctrination, or socialisation, the process is the same. There is no such thing as flashing lights and laser strobes inputting information into the human brain. The process of belief is the same.

The human brain believes what is repeated often, and the younger the process starts, the earlier that becomes life long patterning.

I'm not quite sure why you would think that brainwashing isn't the right word, but the articles and references attached recognise the same thing.
