Loh Down on Science: Special Pandemic Edition


Panicked Purchases

April 21, 2020

During times of uncertainty, reasonable decision-making flies right out the window. Consumers worldwide hoard items -- enough to last years! Even our ancestors had similar survival tactics. Survivors of England’s bubonic plague in the 1600s may not have built 2-ply fortresses. But, they did stockpile what they could find (hello, beer!). But WHY?


Psychologists believe it has something to do with our evolution. We’ve survived millenia by cooperating as a group. Our social skills have gotten us this far. If we see our “tribe” hoarding, we want to hoard too! Although we could fend off large predators with this impressive collaboration, our stores also run out of T-P!
