two signals drive the human spirit: positive and negative vibes.
while at first glance, both might seem like legitimate ways to actuate people, one (negative) is devouring, the other (positive) is enhancing. that is why positive news should be preferred here instead of negative ones.
I'm saying this because I see a lot of very dystopian headlines being pushed around here.
(while at first glance, negative news might seem to get more attention; in the long run, positive news is what sticks with people. be encouraging, not discouraging.) :D
