What is p-hacking, how does it work, and what does it mean for science in general?

I’ve been reading about how some studies that we assume provide us with information about the world actually don’t teach us anything because of statistical manipulation that makes them look more relevant than they are. How does this work?

It’s like shooting at a target with a shotgun with hundreds of tiny pellets and showing people the one pellet that hit the target, in spite of your terrible aim. P hacking would be paying attention to how likely it was for that specific pellet to hit the target, rather than paying attention to how likely any pellet was to hit the target.

It’s a way of interpreting data that is more likely to find spurious correlations than real causes and effects.
