I think seeing negatives vs. positives might make sense from an evolutionary psych perspective. Pessimistic and cynical people can be good at pointing out flaws in ideas/plans/practices while optimistic people can be good at rationalizing beneficial practices and plans. This applies in both prehistoric tribal society and now in the corporate sphere. Not sure if there is a genetic basis to pessimism vs. optimism but I don't think any is more or less valid than the other
