What is common knowledge in your field but shocks outsiders?

More than half the CO₂ emissions of the industrial age have been dumped into the atmosphere since 1990.

@davidho (IT Professional); Hackers don't typically succeed because they have insane technical skills and expensive equipment. They succeed because Linda in Accounting has a lack of critical-thinking skills and/or is careless.

Mmmmm. Yeah I’m gonna disagree with your blame-culture assertion there. Linda in accounting doesn’t lack critical thinking skills. Linda is busy trying to make sure the bills get paid and that sneaky dude who always fudges his expenses doesn’t get away with it. Linda is tired because she’s doing most of the housework and parenting whilst working full-time, and her kid is sick. Linda also has a boss who keeps making gross jokes. Linda makes human mistakes.

@RestlessLipSyndrome @davidho @seawall I agree that many (most) security breeches are human error, of course. But let’s not frame it as people being careless or stupid :-) nobody will ever catch 100% of tricks. We have to design systems with a level of error tolerance in mind.
@nat @RestlessLipSyndrome @davidho @seawall Great deconstruction there friend. Respect to you
