My play group is -generally speaking- irrationally paranoid.
I blame myself. We migrated to EotE from the Warhammer 40k line, where my plots were often filled with doublecrosses, intrigue and conspiracy. Expected. The group is very intelligent, so tossing simple "milk runs" at them is a rare treat. But even then, everyone is a potential bad guy. Checks that succeed with fistfuls of both Success and Advantage still obscure a potential trap. If I say -OOC- "Seriously, all is on the up and up" they don't take it at face value, and if a NPC says IC "Don't go there/do that, it'll get yer killt" they go there/do that, nearly get killed, and it's an instant ticket on the Paranoia Express, like I planned for them to ignore the warning.
So I thought I share this bit of advice from experience:
Uh, yeah. I got noth'n.
