Since we've been kids we've been taught, hopefully, that lying is bad.
Society though normalize it :
- advertisement is pretty much always wrong (to the point of having laws in Japan about food packaging, France about modeling, etc) and the deception is the message
- entrepreneurs promises, nobody reach the goals set to VCs, it's always a lower number no matter the KPI. See https://elonmusk.today where the wealthiest man on Earth, ever, keeps on lying pretty much daily.
- political promises, no need to even give examples of that because it's just pervasive.
so... yeah, we keep on telling our kids "Do as I say, not as I do." then we somehow keep on being shocked that the practice of lying is pretty much happening in every corner of our society.
It's not a technical problem.
