When the unexpected strikes, our brains often start working like we’re being chased by a wild animal. Levels of hormones—specifically, adrenaline, norepinephrine and cortisol—increase, resulting in a range of reactions including increased heartrate, elevated blood pressure and tunnel-vision like focus on the threat. 

This is great if you actually are being chased by a lion. The threat is singular, and your immediate actions are likely singular as well (for example, run fast to shelter). 

But it’s not so great if you’re facing a complex problem in your organization.
