Não é defeito, é feitio!

De certo modo não é novidade, li algo acerca disto nos livros de Kahneman e Gigerenzer.

Veria isto facilmente se tivesse pachorra para ver os programas tipo "O Dia Seguinte"

"In other words, say goodnight to the dream that education, journalism, scientific evidence, media literacy or reason can provide the tools and information that people need in order to make good decisions.  It turns out that in the public realm, a lack of information isn’t the real problem.  The hurdle is how our minds work, no matter how smart we think we are.  We want to believe we’re rational, but reason turns out to be the ex post facto way we rationalize what our emotions already want to believe.
...
When people are misinformed, giving them facts to correct those errors only makes them cling to their beliefs more tenaciously.
...
When there’s a conflict between partisan beliefs and plain evidence, it’s the beliefs that win.  The power of emotion over reason isn’t a bug in our human operating systems, it’s a feature."

E recordo logo Agostinho da Silva e Kotter:

"Agostinho da Silva costumava dizer que é o coração que faz mudar o mundo, não a razão.
.
“Kotter & Cohen começam o seu livro “The heart of change” com:
.
“The single most important message in this book is very simple. People change what they do less because they are given analysis that shifts their thinking than because they are shown a truth that influences their feelings.”"

“People change what they do less because they are given analysis that shifts their thinking than because they are shown a truth that influences their feelings”
