Making predictions about the future is a notoriously tricky business.  It is often done by extrapolating from past trends.  As often as this method fails us, its hard to imagine a better heuristic than the belief that the future will be like the past, only more so.

Extrapolating current trends in combinations that should be obvious yield conclusions that are, to me at least, surprising and inspiring. Here are two trends:

Recent scientific history, say of the last 60 years, has been filled with major discoveries that appear to have vast explanatory power and with widespread technological applications.

The average expectancy of an American is 78 and continues to increase.

If the past is any guide to the future, me and my generation are likely to witness discoveries of the magnitude of DNA, events like men landing on the moon, new ubiquitous technologies like computers and cell phones.

On top of the science, new developments in the social sciences, in society, and in world politics will be ever interesting if not so distinctly progressive.

All manner of surprises await us, so many before we even consider the real breaks from the past, the “unknown unknowns” that open up entirely new fields of endeavor and ways of thinking.

Here’s to the future!

“Once upon a time, there was a man who was convinced that he possessed a Great Idea.  Indeed, as the man thought upon the Great Idea more and more, he realized that it was not just a great idea, but the most wonderful idea ever. The Great Idea would unravel the mysteries of the universe, supersede the authority of the corrupt and error-ridden Establishment, confer nigh-magical powers upon its wielders, feed the hungry, heal the sick, make the whole world a better place, etc. etc. etc.

The man was Francis Bacon, his Great Idea was the scientific method, and he was the only crackpot in all history to claim that level of benefit to humanity and turn out to be completely right.”

The people at Overcoming Bias say the awesome powers of science mean rational people must be extra skeptical of its methods.

I wonder whether another crazy idea will ever be so successful again.  Its enough to make a man want to hang out in the British Museum and put pen to paper for a few decades.

Scott Adams of the Dilbert Blog wonders about this “alleged freedom”.

“In the United States, we have freedom of speech, in the sense that the government won’t arrest you for speaking your mind. Yay for freedom!

But your fellow citizens will happily ruin your economic life if you say something unpopular in public. Some might say that has nothing to do with the right of free speech. It’s an example of free people acting in a free way. But to me, it looks like cutting out the middle man. There’s no point in electing a government to punish unpopular speakers when the citizens can do it themselves, and cheaper. It might look we have freedom of speech to you, but to me it looks like we just found the most efficient system for limiting it.

[Interesting side note: For this post I made a list of opinions you are not allowed to express in this country, and realized I can’t even publish the list without a social and economic penalty that wouldn’t be worth the benefit.]“

I myself have long though that restrictions on the freedom of speech only “count” if they are imposed by the government.

But some life experience and some exposure to such radical thinkers as Alexis de Tocqueville (who noted how Americans treated those with differing opinions in Democracy in America) has made me more sympathetic to Scott’s point of view.

As someone with no job to lose and little fear of social penalty (mostly because no one reads this), I thought it would be interesting to compile the list Scott could not- what are the opinions you just can’t hold without risking your job and/or access to public debate.

1) Outsourcing is good for the American economy

It’s the orthodoxy among economists, but death in the political arena as Greg Mankiw found out when he went from harmless Harvard professor to Bush economic advisor… and back again.

2) There are non-physical, non-trivial differences between men and women

Rather the inverse of the outsourcing question; this is the orthodoxy, I think, among ordinary men and women in everyday life; but its the kiss of death in the academy. Just ask Larry Summers, former Harvard president, now demoted back to Harvard professor after suggesting that men and women have differing abilities in math and science.

(maybe the real lesson here is to not be a professor at Harvard)

3) Genetic variation in intelligence is not distributed randomly

Ie, intelligence may correlate with other factors like (oh no!) race. This is the worst of all, as it brings out the hate from scientists, politicians, journalists, and ordinary people. Just ask James Watson, one of the men who first identified DNA. One response of his to the controversy made it into the Daily Mail:

“Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so,” he says.

One of the sad truths of life is that wanting something good and beautiful to be true is not enough to make it so. (Exceptions to this are really cool and rare as unicorns)

I think that most people fail to realize this or choose to ignore it. Certainly I struggle against it. But if anyone should base their views on what they can prove to be true, rather than what they want to be true, it must be the scientific community. There are other issues where scientists appear fairly dogmatic; global warming is a mild case, evolution a stronger one. But Watson seems to have revealed some of the strongest scientific dogma of all.

That was kind of a tangent… anyway, I’d like to see your own ideas in the comments about what you can’t say in America.

Final quiz prep, in case anyone surprising is among my normally intelligent and educated audience: for those who missed Civics 101, protecting someone’s freedom of speech doesn’t necessarily mean you agree with them; in fact the whole point is to tolerate dissent. For those who missed Logic 101, the truth of an idea not dependent on those who believe it, or even those who put it forward; ie, just because scientists largely believe in evolution or the equality of intelligence across races for unscientific reasons doesn’t mean they aren’t true.

…it’s not just for Calvinists. I’ve been reading Carl Sagan, the astrophysicist, and remembering that there is no shortage of scientific materialists who don’t believe that we have any free will. I wouldn’t have thought they would really have anything in common; but there it is. Two communities that I mostly have a lot of respect for, holding as one of their core beliefs something I would really rather be false. Would you rather be a puppet held by physics and chemistry, or manipulated by a more traditional deity?

I wish I were a real boy!

Watching the PBS documentary on Michael Greene’s The Elegant Universe. It’s fairly well done, though a bit slow and repetitive.
The most common criticism I’ve heard of string theory is that it is not really scientific at all, because it makes no testable predictions. This lack of observability and predictive power makes it completely useless, “not even wrong”. Greene insists that tests will emerge in the future. But the documentary makes the claim that string theorists predicted the existence of a gravity-particle in the 1980’s; and there are now experiments designed to detect these “gravitons” and “gravity-waves” (like LIGO ) I would think this is a great test, except that they completely fail to mention it in the documentary.
