A few weeks ago, I was watching a TED Talk given by this architect/design critic who was basically saying that negativity is a more powerful teaching tool than positivity because, in her words, when you say you like something, even that you really like something, people have a tendency to not care (I'm sure we've all experienced that before...sadface). But if you say you HATE something, automatically people want to know, "why?" It grabs their attention.
I don't know how true this is...I live and breathe negativity; I haven't experienced enough positivity to make a comparison. ^^; But one thing I HAVE noticed is the tendency of style-centric topics on this forum to devolve into 'tropes we all hate' festivals. It's hilarious, and it's fun...but it's also kind of repetitive and a little...intriguing. Why does this keep happening? Is it the power of negativity in action??
To offer a biological/evolutionary perspective on the issue (good god; my psych classes have trained me too well) I would restate that the human brain is wired to focus on and remember the negative example above all else. Your mama tells you over and over not to touch the hot stove, but you never really learn until you finally burn your hand. After you have that first car accident, suddenly all the thousands of safe car trips you've taken in the past mean nothing compared to the fear.
Humans are built to survive, and a good way to do that is to pay attention when bad things happen to you and to other people, so you can avoid them in the future. Which would explain why negativity of all kinds is so interesting to us.
But what's your perspective? And if you believe in the power of negativity, do you also believe it's the way things should be?
