The point is for the audience to like what they're hearing. So it doesn't matter if you avoid the problems Olson has described in the previous three chapters (Don't Be So Cerebral, Don't Be So Literal Minded, Don't Be Such a Poor Storyteller). If people don't like you, they won't listen to you.
Scientists generally feel that they need to play truth-teller to the masses' fantasies. So they tell them things aren't real, such things could never happen, that the universe doesn't work that way. And they strip life from life.
In fact, according to Olson, many scientists have the trait of common villains: arrogance. They think they're smarter than everyone else, so they want to shut up the people who are not as smart who don't agree with them. Or they want to yell at those who aren't as smart (which means those who disagree).
But is it possible to be a scientist
and be well-liked?
A negating profession
Part of the problem, according to Olson, is that science is a "negating profession":
The
entire profession of science has at its core a single word, and that
word is "no." Science is a process not of affirming ideas but of
attempting to falsify ideas in the search for truth...When you give a
scientist a paper, he or she reads it with the assumption that the
writer is guilty of being wrong until proven innocent.
And that doesn't make scientists that popular at dinner parties. As Olson goes on,
You meet scientists who have lost control of this negating approach to the world and seem to sit and stew in their overly critical, festering juices of negativity, which can reduce down into a thick, gooey paste of cynicism.
You see, science is a combination of "creativity and discipline," and both are necessary. Without discipline, scientists spend time on worthless flights of fancy. But discipline without creativity isn't human. It's just cynicism. And most people, i.e. nonscientists, like inspiration and hope, not destructive "truth-telling."
But when it comes to dealing with the public in forums such as debates or blogs or other non-scientist-y forums, scientists sometimes resort back to their negating tendencies. It's hard to be inspirational and full of hope, Olson says, but it's easy to rage against a devil. For scientists, that devil is inaccuracy. But they need to learn to get past merely fighting against the devil and find something to believe in, not just to fight against.
Being likeable
The key is to be likeable, to go for style as well as substance, to go for "yes" instead of "no," to be gracious to those who think differently. We may not like it, but people make decisions based on the person they like the best:
Lacking the time and energy to evaluate the information being presented, people end up evaluating the presenter. They are no longer able to transcend style to get to substance...Style becomes the substance.
So scientists have to be likeable, but there's no manual for how to do that. (And we all know, scientists love manuals!)
If likeability came down to a formula, scientists would figure it out and be the most popular people in the world. Of course, it's far too subjective for that. But we do know likeability is inextricably tied to elements arising from those lower organs [outlined in Chapter 1]: humor, emotion, passion.
But they have to do it. In this age of mass communication, scientists have to learn how to communicate with regular people. And to do that, they have to be likeable.
