Shark attacks isn't really p-hacking though, that's about misinterpreting/misrepresenting a real correlation. P-hacking is finding a fake correlation due to chance because you tested a lot of different things in a smallish dataset, and then reporting that correlation as meaningful without mentioning your negative results or properly explaining your entire process.

This is what I don’t fully grasp about p hacking myself. Say you test variable abc and so on all the way to z. Variable z were found to be significant. Now imagine you had the same data set and just happened to test Z and stopped there, finding it significant.

According to the p hacking concept the former would be potentially unethical while the latter would be great science, however nothing about the underlying data or its association between variables has changed.
