Ok so you said you were "amazed at the speed at which people can be con ditioned"
So, I would say that the important reason why people are wearing masks is not because they are conditioned.
There are very good arguments for wearing masks and these involve science.
That is where science came in,
It's not about conditioning it's about science, not wanting to infect other people etc.
Do you understand now?
