But wait, there's more.
A couple of years ago, six social scientists published a paper describing a disquieting occurrence in academic psychology: the loss of almost all its political diversity. As Jonathan Haidt, one of the authors of the paper, wrote in a commentary:
Before the 1990s, academic psychology only LEANED left. Liberals and Democrats outnumbered Conservatives and Republican by 4 to 1 or less. But as the "greatest generation" retired in the 1990s and was replaced by baby boomers, the ratio skyrocketed to something more like 12 to 1. In just 20 years. Few psychologists realize just how quickly or completely the field has become a political monoculture.
While the paper focuses on psychology, it briefly mentions that the rest of the social sciences are not far behind:
[R]ecent surveys find that 58–66 per cent of social science professors in the United States identify as liberals, while only 5–8 per cent identify as conservatives, and that self-identified Democrats outnumber Republicans by ratios of at least 8 to 1 (Gross & Simmons 2007; Klein & Stern 2009; Rothman & Lichter 2008).
As these studies are now approximately ten years old, it's quite plausible that the gap has widened further over the past decade (as it has in psychology) meaning that these figures most likely underestimate the current left-to-right ratio across the social sciences.
Now, this all comes as no surprise to anyone who's gone to university in the last 25 years, or was in any way paying attention. The state of affairs is as Harris says, there's no doubt. The problems inherent in a monoculture of one politicaly acceptable view are manifold, and obvious.
In fact, Haidt recently reported on a remarkable survey that was conducted among the Society for Experimental Social Psychology, which, as Haidt notes, is:
… a professional society composed of the most active researchers in the field who are at least five years post-PhD. It's very selective—you must be nominated by a current member and approved by a committee before you can join.
As part of the survey, members were asked to identify their political affiliation on an eleven-point scale, from 'very liberal' to 'very conservative'. (One point in the centre and five on each side.) The results are telling. Only 2.5 per cent of respondents chose a conservative point, and only 8.3 per cent chose the centre-point, meaning that 89.3 per cent identified as left-of-centre.
Intriguingly, the least popular point among the left-of-centre points was the most moderate one (5.8 per cent), and the second-least popular was the second-most moderate one (15.6 per cent). More than two thirds (67.8 per cent) chose one of the three points furthest to the left on an eleven-point scale, and more than a third (38 per cent) chose one of the two points furthest to the left. And 16 per cent chose the furthest possible point to the left on an eleven-point scale.
This means that there were almost as many people who chose the furthest possible point to the left as there were who chose all the conservative points, the centre-point and the most moderate left-of-centre point combined (16.6 per cent).
It seems likely to me that there are self-reinforcing mechanisms at work. As the ratio of liberals to conservatives increased, a tipping-point was reached where conservatives were actively excluded from the social sciences, and as they have disappeared the more radical liberals are now outnumbering the moderates to the point where they too are being gradually excluded. In other words, it appears that social science is undergoing a purity spiral towards an increasingly radical left-wing ideology.
Liberalism is the culture of the New York City intellectual elite, among whom are counted publishers, editors, etc. As the years wear on and more old guys retire, the people who replace them are very keen to show they are serious and On The Right Side. Zero new Conservatives are hired, of course, because Conservatives are yucky. Who wants one of Them around? As Harris says, you keep that kind of osmotic pressure going for 40 years, you end up with the present situation. No Conservatives working in publishing, no Conservatives joining the literature clubs, no conservatives voting for awards.
Those damn Conservatives intruded! How dare they?!
This year the Sad Puppies have stopped intruding, and the Hugo Faithful are still reacting to what we did two years ago. With no one to introduce anything different into the mix, the SF/F awards season is looking extremely Lefty/SJW this year, as it always does.
