All exaggeration intended, but scientific and unscientific studies alike are coming up with the same conclusion: People who read deeply are pretty much better people in every way.
A recent post over at TIME emphatically states that deep reading creates more real life empathy (the opposite of jerkathy). Over at Elite Daily they have this to say in regards to studies done by leading sciencticians:
[People who read deeply] can entertain other ideas, without rejecting them and still retain their own. While this is supposed to be an innate trait in all humans, it requires varying levels of social experiences to bring into fruition and probably the reason your last partner was such a narcissist.
In case you are still hemming over the definition of deep reading, let me clear things up for you. (Let me reassure you, yes, you suck.)
