> This was unsettling. It was impossible not to question if I too were an unreliable narrator of my own experience. Was I hoodwinked by the screens of code flying by and had no way of quantifying whether all that reading and reviewing of code actually took more time in the first place than just doing the thing myself?

I don’t understand why this was so surprising to people. People are _terrible_ at self-reporting basically anything, and “people think it makes them mildly more productive but it actually makes them mildly less productive” is a fairly common result for ineffective measures aimed at increasing productivity. If you are doing a thing that you believe is supposed to increase productivity, you’ll be inclined to think that it is doing so unless the result is dramatically negative.
