@ThreeBadgersInATrenchcoat Good points made by you and @Wetrix
I was envisioning a scenario as to when someone comes across a new lesser-known thing (object, idea, person) they rely on heuristics for a judgement, especially around trust.
There is a lot of psych research around it, and it often boils down to familiarity.
And isn't always rational.
For eg- I'd trust my mom over a rando even tho she might me lying coz I know her.
