And not even qualified by a "possibly". This rather smacks of a knee

Be realistic. Every experiment is done to prove or disprove a
hypothesis. In this case it seems there hypothesis is not really about
code at all but about how human perception works. I can't imagine a

But human perception no doubt hasn't changed. It would be interesting
to see the experiment duplicated for C and other languages but in the
absence of those results, using the results one does have instead of
blind prejudice seems reasonable.

I thought they rated it low on readability. What are you looking for
a tirade? I think your measure of expertise is flawed.

That does indeed seem to be a deficiency. Whether you view it as a serious
one is up to you.

Again, thats a pretty serious accusation to make about some work you
don't know much about!

Ah well, this does smack of tilting at windmills on the part of Mike
Cheponis, which is why I, and probably others haven't participated
before. I think he has no chance of getting this through, but I
think he is right and applaud him for trying anyway.
I can't help but think that 8 spaces was based initially on lazyness.
In the days before smart editors, tabs were a lot easier than counting
spaces. The original reason no longer exists and the likelihood of
such a pragmatic decision being anything near optimum for other factors
seems slim to me.
