You're minding your own business, traversing a city sidewalk, when suddenly you see a physical altercation — and it involves a man and a woman.
Do you intervene?
Ah, but hang on a second. There's a twist.
What if the woman is beating up the man?
So...do you intervene?
A hidden-camera experiment by the ManKind Initiative claims that onlookers in public react in strikingly different ways depending on the aggressor's gender, The Mirror reported.
In the first case, filmed in a London park, a male actor attacks his "girlfriend" in front of shocked witnesses — and they get involved very quickly.
There's a threat to call police, and another witness adds: "You don't have to put up with that honey, he's not worth it."
But in the second scenario when the female is the one doing the pounding...
...the crowd just stares. Some even laugh.
So...how would you respond? Let us know in the comments below.
And here's the clip. (Content warning: Quite a few f-bombs and other rough language flies...):
