As is tradition: 
On a more serious note:
I feel that between the false consensus effect, or worded specifically for software developmentā¦
ā¦and to some extent good old confirmation bias thereās a perfectly reasonable explanation why there is a certain amount of āBetriebsblindheitā (German for āorganisational blindnessā) in those who create a product. This is something everyone who writes software or creates some product in some other way needs to look out for.
(to be clear, I am not saying @dreev got a monopoly on this. Absolutely not. I just used him as guinea pig for introducing the topic of how when you make a product it is hard to not fall victim to the aforementioned effects. I would know because I for sure have experienced them extensively. From both sides )
