Comment So Which is It? (Score 1) 188

But, if there were enough energy to push the universe over the hill and into the deeper energy valley next door, the universe would simply, and catastrophically, collapse ... For any wannabe universe, this is very bad news — the newborn universe would appear as a Big Bang, the Higgs field would become overloaded with an energetic inflationary period, and the whole lot would vanish in a blink of an eye.

This isn't true.

Etymology of "incentive":

Middle English, from Late Latin incentivum, from neuter of incentivus stimulating, from Latin, setting the tune, from incentus, past participle of incinere to play (a tune), from in- + canere to sing

Etymology of "incite":

Middle French inciter, from Latin incitare, from in- + citare to put in motion

The two words come from completely different Latin roots and arrived in English from completely different sources.

There's all kinds of psychological research showing that people's perceptions of what motivates them is wildly different from what actually motivates them:

Why People Choose Coke Over Pepsi

In a study of exactly that question, four French and four German wines, matched for price and dryness, were placed on the shelves of a supermarket in England. French and German music were played on alternate days from a tape deck on the top shelf of the display. And indeed, on days when the French music played, 77 percent of the wine purchased was French, while on the days of German music, 73 percent of the wine purchased was German. Clearly, the music was a crucial factor in which type of wine shoppers chose to buy, but when asked whether the music influenced their choice, only one shopper in seven said that it had.

In another study, subjects were given three different boxes of detergent and asked to try them all out for a few weeks, then report on which they liked best and why. One box was predominantly yellow, another blue, and the third was blue with splashes of yellow. In their reports the subjects overwhelmingly favored the detergent in the box with mixed colors. Their reports included much about the relative merits of the detergents, but none mentioned the box. Why should they? A pretty box doesn’t make the detergent work better. But in reality it was just the box that differed – the detergents inside were all identical.

Comment What's the Influence of Crappy Polling? (Score 4, Insightful) 254

62% of the more than 18,000 U.S. consumers it polled said social media had no influence on their buying decisions.

I hate polls that take some factual statement that is either objectively true or isn't, and then ask people whether they think it's true, as if that tells us anything about the factual matter rather than just the biases of the poll sample.

Social media advertising either influences or it doesn't. And it will influence or it won't regardless of whether zero, half, or all of the country thinks it does.

I was a engineering major, and most of my freshman/sophomore classes were in a big room with 300-400 students watching a professor I never directly met the entire semester giving lectures that might as well have been on You Tube.

All the interaction was provided in weekly "break out" sessions taught by completely unpaid grad students.
