2018 state of Haskell survey results

The [2018 state of Haskell survey][1] opened at the start of November and closed a few days ago. It was the second annual state of Haskell survey. This year the survey was co-sponsored by Haskell Weekly and Haskell.org.

Last year the [2017 state of Haskell survey][2] received 1,335 responses. This year we received almost four times as many. However a large number of the responses appeared to be submitted by a script. Of the 5,096 responses, 3,735 were identified as problematic and removed from the result set. That left 1,361 legitimate responses, which compares favorably to last year, especially when you consider that this year's survey was much longer. To everyone that participated in the survey: Thank you! You feedback is hugely valuable.

I am extremely disappointed that someone decided to submit thousands of bogus survey responses. Apparently they wanted to tip the scales on a few divisive issues in the community. Fortunately their attack was not very sophisticated, so it was easy to identify and ignore their responses. ([This function][5] shows you exactly how the problematic responses were identified.) Even so, it has two profoundly negative impacts: One, it casts doubt on the survey responses as a whole; and two, it means that I'll have to devote time to countering attacks like this in future surveys. That being said, I have confidence in the filtered survey results and I hope you do too.

This post will graph the answers to the multiple-choice questions. I will not attempt to summarize the answers to free-response questions. I encourage any interested parties to download the raw results, do their own analysis, and share their results. You can download the anonymized responses as a [CSV][3], which is licensed under the [ODbL 1.0 license][4].
