I don't have any good links or books unfortunately. There are a few people close to me that have a really great ability to empathize with others. They instantly understand social situations that will take me forever to get the dynamic. They respond to the needs of others much more quickly. I've tried to learn as much from them as possible - and often remember them when making decisions that have an impact others. But, I still have a long way to go.

EDIT: I realized you are probably looking for that study. I don't think there is a free online version but you can purchase or read the abstract here: http://www.sciencedirect.com/science/article/pii/S1053811912...

It's just an intuition, but solving problems as a job might make you see every issue or bad situation as something to solve.

Not that it's wrong, but the focus slightly shifts from what the people are feeling to how the problem could or should be solved, and we might take less time or emotional resource to empathize. The situation itself can also be seen less as a tragedy than some sad transitory state waiting to be solved, and we'd be less sorry for someone if somewhere we think it might be just temporary.

I'd too would love to find studies or evidence about this subject.
