[Hasknewbie]

I can't help but notice that this author, seemingly concerned with correctness, also wrote a post about static typing's benefits being unclear, with his argument there again based on an arbitrary and completely unscientific graph pulled from another Medium blogger.

He seems to base his views on the hearsay from his Javascript monoculture, while ignoring the more relevant literature like Code Complete or (when it comes to TDD) Making Software: What Really Works, and Why We Believe It, both books basing their claims on empirical research. Making Software's conclusion is that TDD can help, but does push complexity upward (i.e. programs end up with simpler components so as to make TDD easier, but with a higher numbers of them and therefore more dependencies between them) so resulting bugs will be harder to track.

But it's hardly surprising this article is poorly researched: it's just rehashing TDD pablum for self-promotion, there is not a single original thought in there.
