Results of 2018 Reader Survey

Filed under: Blog,Reader Survey — Razib Khan @ 3:31 pm

There are currently 104 people who have responded in various degrees to the reader survey.

If I limit to South Asians only, the modal reader is an Indian national, though not overwhelmingly so:

In terms of religious identity, Hindus are modal, but those who are not religiously identified are very common (I selected this latter option despite my “Muslim name” and familial cultural background, as I am not not part of any Muslim community and my children have no affinity or affiliation with that identity):

South Asian readers of this weblog are very skeptical of God:

The communal background is what you’d expect:


About 20% of South Asian respondents identify as Hindu nationalists, while average self-reported socioeconomic status is high.

About half of the readers of this weblog are European/white. They are more irreligious and more religiously skeptical than the South Asians. Their self-reported socioeconomic status is somewhat lower.

21 respondents said they were Hindu. Only 1 was a convinced theist:

Among the Muslim respondents 4 out of 6 seem to identify as agnostic or atheist.

Of the self-identified Hindus, 8 out of 21 were Hindu nationalists. The caste breakdown of those who said they were Hindu indicates that South Asians who do not identify with Hinduism are less elite on the varna ladder:

Overall, the sex ratio is one notable aspect of this blog’s core readership: 95% are male.

About 50% of the traffic on this website is from American IPs. But 40% is from Indian IPs.

Reader survey results, biologists vs. non-scientists

Filed under: Administration,Reader Survey — Razib Khan @ 2:54 pm

There are now over 400 responses to the survey. Here is a link to the responses in CSV format. If you import this into R, an extra parameter in regards to encoding may be necessary:

responses=read.csv("responses.csv",sep="\t",header=TRUE,fileEncoding = "UCS-2LE")

I decided to separate the respondents into two categories, biologists and non-scientists (therefore, excluding other types of scientists from further analysis). You can see the filtered responses for biologists and non-scientists yourself. Below are some comments on interesting differences.

Non-scientists Biologists Completed Doctorate 57 19 Completed University 23 38 Feminist 36 46 Important to prenatala screen? 83 75 Abort if 90% chance Down syndrome? 79 83 Abort if 90% chance 80 IQ? 58 54 GMO should be labeled 45 39 Drink every day 16 30 Never drink 13 3 Non-environmental race differences in personality 64 54 Non-environmental race differences in intelligence 69 57 Non-environmental sex differences in personality 85 77 Non-environmental sex differences in intelligence 58 39 Overpopulation is a major problem we are neglecting 28 44 Believe in policy responses to fertility differences across groups 33 13 Gattaca is unrealistic 28 41 Blogs read regularly Bad Astronomy 26 24 Cosmic Variance 19 15 Loom 22 32 Ed Yong 24 47 Pharyngula 16 24 Why Evolution is True 15 28 Marginal Revolution 36 18 Kevin Drum 11 3 Instapundit 14 6 Steve Sailer 48 26 Matt Yglesias 17 10 DailyKos 7 7 RedState 2 3 Sandwalk 4 15 John Hawks 43 43 Dienekes 47 40 Panda’s Thumb 8 3

It makes sense that people who say they’re biologists tend to be very well educated. One thing not evident explicitly in the table is that the biologists who read this weblog tend to be more conventionally Left-liberal in their views, and I think that explains some of the differences in response to questions such as ...

I can’t send you to a direct link, so here are the results. Some of the results need to be crunched by me unfortunately. But here’s a sample (yes, I didn’t do much more than the basic R density plot).

Goal met on the reader survey, now the data….

We’re well north of 500 for the reader survey. Thanks to everyone who participated. I’ll let it run until Saturday morning and then close it. I figure if you aren’t reading the blog at least once a week right now you’re not a core reader anyway (yes, I know that people get busy!). But I did promise to release the raw results at some point. I’m doing so now. It’s in Google Docs.

2011 Reader Survey: GNXXP vs. GNXYP edition

Filed under: 2011 Reader Survey,Blog,Reader Survey — Razib Khan @ 2:02 pm

A typical female GNXP reader?

We’ve moved north of 400 responses on the reader survey. I think the goal of an N of 500 is totally viable. In the past I’ve actually pushed it well north of 600 by leaving the survey open for a while. I know there are some people who drop in once a week or so, or don’t have time or inclination to participate initially. If you want to participate: just click here! It will take ~10 minutes, and no answer is mandatory.

There are already a few robust findings though. GNXP readers are well educated and smart. About 60-70 percent aver that they are irreligious, and 85 percent reject the existence of the supernatural. Over half have backgrounds in the natural sciences. None of this is too surprising. I’ve been taking surveys of the readership since 2004, and the main change has been in politics. Whereas in the mid-2000s libertarians were the largest contingent, now Left-liberals are, though there remains a sizable libertarian minority.

One of the most consistent findings on this weblog has been the sex ratio: the proportion of ...

2011 reader survey preliminary results

Filed under: Blog,Reader Survey — Razib Khan @ 10:57 pm

My sample size for the reader survey is now ~200. I’m aiming for ~500. If you are a regular reader of this weblog, please consider filling out the survey. The software is telling me that the average reader is taking about ~10 minutes. All questions are optional, so you can quickly skip over confusing ones or those which you don’t want to divulge.

The results so far are here. At least for the questions which weren’t open ended. I added a lot of open ended numeric questions so that I could run some scatterplots and more natural statistics (i.e., I don’t have to convert categorical responses into numerics and so forth).

To give a taste for the kind of stuff I’m running on the nerd-heavy data set I thought I would explore how # of sexual partners relates to age and IQ. First, let me admit that I assume that the IQ distribution of the readership here is somewhat artificially shifted upward (to the right of the distribution). Those with higher IQs are more likely to know their IQs. And whether unconsciously or consciously individuals will almost certainly self-report results which are drawn from the higher range of their results ...

Reader survey results: politics

Filed under: Blog,Reader Survey — Razib Khan @ 10:38 pm

Since the reader survey is topping out in response, I though I’d report some of the results. Since I’ve been doing these surveys my readership has exhibited a few patterns, and I was curious as to any changes since moving to Discover. Not too much has shifted. Instead of 15% female, as was the case for years, the readers are now 25% female. It looks like ~10% of the readers know this website only through Discover. Feel free to browse the results yourself.

I think the most interesting aspect for many is the political diversity. Generally the readership is split between Left liberals and libertarians. Though there are a small number of conventional conservatives, it is very rare to find those who are socially conservative and fiscally liberal. These “populists” tend not to be as intelligent as the other combinations, and so I suspect that’s why they’re not well represented on the web, among my readership, or the political elite of the United States in general (for what it’s worth, I’ve been moving in a more populist direction over the years, starting from a libertarian stance).

First, a few summary statistics. I asked readers their index of liberalism, with 0 being as conservative as possible, 10 as liberal, and 5 in the middle. I asked on two dimensions, social and economic.


Median – 8
Mean -7.4
Standard Deviation – 2.48


Median – 5
Mean -5.01
Standard Deviation – 2.74

The correlation between social and economic liberalism was 0.37. Here is a chart which illustrates the different distributions:


I’ve smoothed a bit, but it’s clear that while there’s several modes in the economic liberalism distribution, there’s a strong liberal slant on social issues. Not that surprising. But I wanted to look at the combinations, so I created some bubble plots. The size of the circle is proportional to the weight of the particular political combination within the set (or subset).

First, the whole data set.


You see four quadrants. The plural majority of readers are liberal, followed by libertarians, then conservatives, then populists. Remove the centrists (those who selected 5 on either social or economic responses) and summing up the numbers in the quadrants, here are the percentages:

Liberals – 40%

Libertarian – 28%

Conservative – 11%

Populist – 3%

(the rest are in the borderline zones)

Now let’s look at the subsamples and how that impacts distribution.


Female readers tend to be more liberal.

I’ll just leave you with the rest of the bubble charts with minimal comment. But if you want to know something about the data, ask in the comments. Doing the analysis isn’t usually that hard, but I don’t know what people want to know (virgins are young, but not different than the rest of the readership).

Reader survey results: Science vs. social science vs. humanities

Filed under: Blog,Reader Survey,Survey — Razib Khan @ 10:51 am

About six months ago I did a survey of the readership of my two Gene Expression blogs (before moving to Discover). The N was around 600. You can view the raw frequency results here. One of the issues which I was curious about: did the disciplinary background of readers have any major correlates with responses? So I created three categories from the data on disciplines:

-Social Science
-Not Science

Social science had its own section, but for science I amalgamated those who studies Math, Engineering, Natural Science and Medicine. The balance were under “Not science.”

Turns out there’s no big difference, except for in calculus. A particular type of person must be attracted to the substance and style of this weblog (I suspect the biggest substantive difference between the readership and myself is that I’m on the extroverted side). I’ll probably post a survey for tomorrow, mostly to see how much Discover has changed my readership. But periodically I’ll also look at the results for previous surveys like this.

Note: Some of the results do not add to 100% because I rounded.
