As someone who works in healthcare, it must be like a healthcare/medicine/biology thread popping up for me.

You'll never see so many people so certain they were right despite lacking the most basic knowledge on the topic.

I've found that you need come into HN comments with a baseline amount of skepticism and then increase skepticism the further the topic strays from being purely about software development.

Even then, the things software developers believe about their own profession should be taken with a grain of salt.

Hence the baseline skepticism :)

It conflating data with knowledge. "Because I deal with X industry data, I understand X industry"

That attitude is the main beef I have with highly qualified, up to PhD level, data scientists. they could bring so much to the table, in any domain, by working with the domain experts. Instead of doing that, and trying to learn, most (basically all I encountered so far) try to understand any domain they encounter based on their data sets and some first principle. Kind of re-discovering gravity, and then expecting praise for being geniuses for doing so.

A shame, really. Because my skill in big data analysis stops at what Excel can do without macros. I'd love to get more data insight, simply turned out that it is hard to get.
