The University of New South Wales researcher says a grumpy person can cope with more demanding situations than a happy one because of the way the brain "promotes information processing strategies".
Information processing strategies! That rings the bullshit bell in my grumpy head, loudly and clearly. I don't intend to discredit the study. It is unfortunate that everything in psychology seems questionable. Many of these studies appear misleading even when they may lead us down a useful path. That's this subject's bane.
