Look for yourself in it.
Short form? Nothing.
I mean, yes, you can absolutely reduce the frequency with which you get fooled through diligence, skepticism, curiosity and empathy, but nothing will fully protect you.
The thing about risk management is that THINGS WILL GO WRONG. The naive thing to do is to try to make it impossible for that to happen, but life is inconvenient that way, and prevention has diminishing returns.
Rules like "Don't make decisions when you're upset" are a good example of strategies for dealign with this.
That's actually good news. States are hard to build rules around. Actions are simpler.
You *have* rules, even if you don't think about them. But if you don't think about them, the rule is probably "This caused an emotional spike, so I will share it!" or something similarly flawed.
On the other hand, you can hardly vet everything you reshare with academic rigor, nor should you be expected to.
* I actually read it
* I've checked that the website isn't trash
* I've stripped tracking bullshit from the URL
None of those fix everything, but they could offer a HUGE improvement, depending on your patterns.
And, of course, exercise curiosity and compassion in your dealings. Prevention alone leaves holes that prevention + mitigation can fill.
