Earlier quoted context omitted.

* blog refers to husband--should it be a "she"?

Isn't the person being quoted a man? >Recently, my husband pointed me to the work of a well-known sociologist, Duncan Watts, earlier at Yahoo! Research, who explains why people exhibit such behavior. Here is my favorite part of his TED talk

Spot on. My apologies.

"Rocket science" was esoteric and super-complex, at least to the educated masses in the 40s and 50s when this phrase seemed to be coined (http://www.oed.com/viewdictionaryentry/Entry/166731?print). Think secret German technology, V2s, von Neumann, the space race, etc. Nowadays we tend to regard the complex Curiosity landing as ordinary.

But the more important point is: It's never pointed in the OP why rocket science is simpler than social problems, e.g. solving world hunger (didn't watch the linked TED talk, though). I think that the reason is that most social problems are "Wicked Problems" (http://en.wikipedia.org/wiki/Wicked_problem). The most important difference between a problems such as solving religious extremism and putting a satellite in orbit (or nuclear fusion or brain surgery) is that in the latter case you can isolate affecting factors and study them in (relative) isolation and sub-problems are well-defined and have well-defined answers, at least compared to social problems.

Rockets used to be hard. Really hard: they mostly blew up, especially when the various agencies were trying all sorts of weird and wonderful fuel / oxidiser combinations in the search for the best possible specific impulse. See the book "Ignition!" by John D.Clark for some of the details.

Interestingly, poking Google's ngram search suggests that whilst the phrase "rocket science" saw a little use around 1900 (I've no idea why: HG Wells?) and some use around the 1940s and 1960s, the phrase "not rocket science" is a far more recent coinage & only appears in the text corpus from the 90s onwards:

As an economist, I salute this post. While common sense will get a person far in life, strategic decision making is a hard process to model.

That is probably the reason new models are en vogue every other decade.

Not quite. Models advance as their conclusions are shown to not hold in reality.

You may be thinking about macroeconomics, in the which there seems to be a fad cycle of models, and a hyped up difference of assumptions. I assure you macroeconomics doesn't actually have a fad cycle.

The rocket always lands as predicted? He didn't pay much attention to the Space Shuttle accidents, did he? Perhaps he's referring to ballistics. Rocket science generally refers to designing the rockets, which to this day sometimes blow up, lose engines, spiral off course, and suffer various other catastrophes.

Men can have husbands, too, you know.

Rocket science is hard because the slightest error will trash your multi-billion-dollar mission. See Feynman and the O-Rings, for instance. Ironically, social science would be easier if it was that rigid. What makes it hard is that even very bad models seem to sort of explain some things, sometimes, or make predictions that come true despite the model being blindingly wrong and stupid, instead of blowing up badly. And a bit more controversially, it doesn't help that social science's "blowups" can be a lot more subtle, and frequently actively shuffled under the carpet. Sometimes it seems like a bad idea in economics or social science can't be discarded until it has completely destroyed an entire civilization, and even then some of them keep popping up... of course, there's little agreement on exactly which ideas those are.

I never liked this phrase; my friend & I (as probably many other HN'ers) were building small solid-state fuel rockets at the age of 15. There's nothing inherently difficult in the basics of rocket science and rocket engineering. Frankly, I find cooking more difficult than making a solid rocket motor land at my neighbour's backyard.

Wasn't the rocket science done by the people who made the solid rocket fuel tube thing?

There's a distinction between engineering (icy o-rings) and science.
