Easy enough to believe, but has anyone dug on this, or checked through the data, the source?

It's important. If you just accept something as a fact because it directly agrees with your ideas, biases and expectations, you become highly susceptible to psyops.

I'm not doubting this per se. Rather, my default position is, and has to be, to not just accept something because it ticks all the right boxes in my expectations and bias folder.

Why? Because those targeting us KNOW what our expectations and biases are, and they utilize them to attack and undermine us constantly.

The only real defense against such psyopery is to simply not believe or 'just accept' a thing without actually digging or knowing what the verifiable facts are.

Anyway, sauce:
