Do you guys think meditation was pushed by an anti-science crew?
You can do a simple google image search for 'meditation' and conclude the target audience is female. As a man used to firing neurons to figure out if a statement is true or not, you can easily feel how meditation numbs the mind if you give it a shot, destroying your brain's ability in the long term to separate reality from non-reality, which is a perfect slave mentality.
It's very reasonable to expect productivity to be very low for meditators. Meditators can't work on their own. Every single meditation community is amazingly brain dead. In philosophical terms meditation is like the reverse of Plato's/Socrates Allegory of the Cave, it is a man going from enlightening to darkness and reversing himself into a dark silent creature observing meaningless uninteresting shadows in a cave wall until his death.
I really wish I'm wrong about this, and that a meditator here on Veeky Forums will use his gained brain powers to fully and exhaustively convince me I'm wrong along with explaining how meditation increased his general productivity.
