Yet the requirements for being a "movie star" consist of being good-looking, and having a talent for mimicry. Neither of those attributes would necessarily make one's political opinion worth listening to.
And movie stars themselves are -- quite often -- some of the most narcissistic, needy, vacuous, temperamental, diva-like, uneducated morons around.
All of these traits are negatively correlated with having a calm, level-headed, rational, numerate approach to problem-solving.
So why do we listen to actors and actresses? And why don't we listen to people whose opinions might be worth something?
For instance, engineers. They understand how things work; and they know how to make things that are efficient and durable. I'm not talking about people like Steve Jobs, who took credit for a lot of other peoples' ideas, or Mark Zuckerberg, who essentially stole the idea for Facebook from those twins. I'm talking about, for instance, the guy who made the flat screen TV, or the guys who actually made those chips faster at Intel, or the NASA engineers who attended to all the details of the spacecraft which landed on Mars. These are all guys who do their jobs quietly, responsibly, and intelligently.
How do they feel about getting us more involved in Middle East wars, or gun control, or affirmative action, or the Pacific trade agreement? We should listen to them, not Susan Sarandon.
Or doctors. You need both brains and discipline to get the grades and MCAT's necessary to get into med school, and then get through four years of med school. If we want a brainy, disciplined foreign policy, we should listen to them. Not Sean Penn.
Or crossword puzzle constructors, who are able to fit things together in clever ways. Being a cruciverbalist is the sort of job that results in genteel poverty, but it still takes a lot of brainpower to make all those words mesh seamlessly.
Physicists, mathematicians, biologists, neurophysiologists, and chemists all understand the inner workings of things, and have a deeper understanding of how our world works on at least some level. Which means they probably have, on balance, a better sense of how things work at other levels as well.
The people who come up with the questions on standardized tests understand how intelligence works, and people who are interested in that subject are almost inevitably intelligent themselves. So their opinions on political matters will probably be likewise.
If we do want to hear what Hollywood has to say, let's listen to the screenwriters, since they're the real brains behind the movies. (It's not the directors or producers or actors.) But we'd have to interview them anonymously, so that they wouldn't have to be worried about being blacklisted by Hollywood by giving the wrong opinion.
But our media isn't interested in what engineers, or chemists, or mathematicians have to say. They prefer the rantings of a drug-addled, needy, insecure, self-righteous, hard-partying actors -- who happen to be good-looking, or at least were at one time.
