Seneca Effect
Description
"Don't you stumble, sometimes, into something that seems to make a lot of sense but you can't say exactly why? For a long time, I had in mind the idea that when things start going bad, they tend to go bad fast. We might call this tendency the "Seneca effect" or the "Seneca cliff," from Lucius Anneaus Seneca who wrote that "increases are of sluggish growth, but the way to ruin is rapid."
