Further survey results

Filed under: Administration,Survey — Razib Khan @ 12:36 am

I have now reformatted the responses into a csv file. So you can do something boring like create a scatterplot with Excel, as above. Or, you can import into R and dig for more interesting patterns. Here is an updated to the PDF which shows you the simple non-crossed results.

Also, out of curiosity I separated respondents into geneticists vs. non-biologists (so I exclude biologists who are not geneticists from this analysis). First, here are the non-biologists on race:


And now the geneticists:

 

For what it’s worth, I agree with the 66% of geneticists. The sample size is small and biased, but still interesting nonetheless.

Gene Expression Brave New World Survey

Filed under: Survey — Razib Khan @ 8:35 pm

A few weeks ago I mentioned that I wanted do another survey. I’ve done a fair number of reader surveys since the mid-2000s of my readership. So, for example, I know that you’re politically well balanced, except for social conservatives (who are very underrepresented). You are also extremely male, pale, well educated, atheistic, and prone to being virgins at a higher clip than your age might suggest. So I didn’t want to overload on demographic questions this time. Rather, I wanted to know about specific responses to specific controversial questions. So I titled it the “Brave New World Survey” this time, because of the focus on uncomfortable questions and the like.

Mostly, I’m tired of arguing with readers about what is, and isn’t, controversial. My readership has a lot of intellectual oddballs (probably because as an atheist brown conservative I am one). So I assume I’m sampling from the extreme end of the pool in terms of openness to heterodoxy, so we’ll see how it shakes out.

I haven’t used this survey software before, so take that as a warning. I put the survey as an iframe below the fold, but it didn’t work too well. So please go ...

Survey on genetics knowledge

Filed under: Blog,Survey — Razib Khan @ 2:23 am

A regular issue that comes up on this weblog is that many of my posts are difficult to understand. I am aware of this. Unfortunately a problem is that there is a wide variation in fluency in genetics knowledge among the readership. To get a better sense I have created a survey with 60+ questions. It may seem like a lot, but the questions go fast because there are only three answers to each, and you should immediately know how to respond. I will likely use these responses to guide me in future “refresher” posts and the like. The questions range from relatively simple to moderately abstruse. That’s by design. Thanks.

Note: The survey will not show up in the RSS, so please click through!

Survey on personal genomics

Filed under: Genetics,Genomics,Personal genomics,Survey — Razib Khan @ 10:25 am
Just got this email, and I thought I would share with my readers: I’m a biologist from Germany and together with 2 fellow biologists I’m currently working on a project that evaluates the sharing of raw data from DTC-genetic-testing companies like 23andme. I was genotyped myself and have already published the data set on GitHub [...]

Who knows heritability and what do they know

Filed under: 2011 Survey,Blog,Survey — Razib Khan @ 6:04 pm

Heritability is a fraught topic. It comes up repeatedly on this weblog, but even long time readers can be confused as to its implications, as evidenced by the incorrect inferences made from their own understanding of the concept. The most common problem is that too often people think that heritability is just a scienced up version of the colloquial idea of some traits being “more genetic” or “less genetic.” It’s not that at all. Traits totally specified in their details by genetic pathways can be non-heritable. That’s because heritability looks at the association between parents and offspring on a trait and attempts to separate the population-wide proportion of the variation attributable to genes and not attributable to genes. When you have a genetically specified trait, like the number of human fingers, you have no real variation within the population to work with (with some rare exceptions). It doesn’t make sense to talk about the heritability of the number of fingers, because this is a fixed trait in the human species.

In contrast, height is a perfect trait to illustrate heritability. Unlike behavioral or cognitive traits its measurement is clear, ...

Summer 2011 Gene Expression Reader Survey

Filed under: Blog,Survey — Razib Khan @ 10:13 pm

I’ve been taking surveys of the readership of this weblog since 2004. Here is my last one, from the summer of 2010. Before I moved to Discover I also did one in the winter of 2010. Here’s a reader survey from the winter of 2009. Another from 2005.

I set up a survey with a new service this time. I did integrate some of the suggestions of commenters as well. One difference between this survey and previous ones is that I have a lot more free-form text boxes with numeric answers. So you give your specific age or income, instead of selecting from a category. The survey shouldn’t take more than ~5 minutes, as many of the questions are yes/no, or very simple, such as your highest education attained.

I’ll post the first results within 24 hours, and probably post the raw files at some point in the near future if you want to crunch them yourself. I set it up so it goes from banal demographic questions in the beginning to more detailed and somewhat esoteric queries by the end. None of the questions are mandatory.

You can complete the survey at this link: http://questionpro.com/t/ACQlIZK0wT.

Reader Survey, summer 2010

Filed under: Blog,Survey — Razib Khan @ 2:51 am

So that reader survey that I mentioned last week is done. I’m mostly interested in seeing the changes since I’ve moved to Discover from ScienceBlogs. I assume that the standard 85% male readership has shifted somewhat toward more balance, but I don’t know. Many of the basic demographic questions (sex, race, age, etc.) are the same, but I swapped out ones I usually ask with others. At this point I’m rather sure that a huge proportion of the readers of this weblog are introverted nerds, so I’m not going to ask about personality type and what not. I took some reader suggestions, so there are questions about what you read, as well what your somatotype is. I converted the political question to a 0 to 10 scale that I wouldn’t have to recode if I did a scatter plot, and also so that it’s a little more fine-grained.

As usual all questions are optional. I timed it and should take you 5 minutes max, though I guess I can’t account for lack of clarity in prose. If you don’t see your exact response, but want to respond, I think it is totally fine to give the closest equivalent.

To take the survey, click here. After you’re done it’ll bring you back to this website. You can review results here.

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:

-Science
-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.

Who are you….

Filed under: Blog,Survey — Razib Khan @ 3:55 pm

Edmund Yong has rebooted the “Who are you?” meme. I’ll quote him:

So let’s do it again. In the comments below, tell me who you are, what your background is and what you do. What’s your interest in science and your involvement with it? How did you come to this blog, how long have you been reading, what do you think about it, and how could it be improved?

I will try and be a little less…abrasive…on this thread in relation to comments, so feel free to let your hair down and “de-lurk” :-)

That being said, I do take surveys of my readership periodically, so here are some of the demographic breakdowns which I have from a survey I took last winter….

-20% of the readership responded that they’d been reading GNXP for more than 4 years

-50% have at least a master’s degree (22% have doctorates, 11% professional advanced degrees)

-Nearly 50% of university degree holders who read GNXP have a background in science & engineering (science = natural science + mathematics)

-78% are atheists & agnostics

-60% have no religious identity

-70% live in the United States of America

-80% are of European ancestry

-86% are male

-35% are on the political Left, 30% on the Right, and 25% Libertarian

-60% have no children

-12% are virgins

-82% have taken calculus

The above includes both GNXP weblogs. The sample size is north of 600 (the omission rates varied by question).

Gene Expression Survey

Filed under: Survey — Razib @ 1:04 am

That time of the year. Please take the Gene Expression Survey. I’ll put up the analysis and the csv file next week. I have the usual questions, but also added a few more that might seem a bit weird. There are 30 questions total, and you don’t need to answer all of them, but as I said the more you answer the more data there’ll be. I did a trial run and it took less than 5 minutes; most people can answer a question about their sex or religious identity pretty quickly.

Update: You can view the results of the survey here.
