Thinking Fast and Slow speaks to the Availability Heuristic - we care more about issues that are presented to us and are available in recent memory even if they're objectively less important than other issues we know about but aren't as readily available to our thinking. The press we expose ourselves to determines what we think is important.

I didn't get all the way through Thinking Fast and Slow before I had to returned it to the library, but it's fascinating and I look forward to finishing it - and likely re-reading it.
