People are torn over viral red button vs blue button debate and what you choose says a lot about you

While it was once ‘black and blue or yellow and gold’ it seems the hot viral colour debate nowadays is simply ‘red or blue’.

Only in this case it’s not about choosing what colour you think something looks like, but rather something about your actual morals. Oh yeah, we’re getting deep here LADs.

It’s already been tipped as an ideal first date question or to suss out the vibes of your new colleagues at the desk.

The ‘red button vs blue button’ is one that does the rounds every now and again, supposedly telling us something to do with psychology.

Essentially, as posted on social media, it poses the scenario of everyone in the world having to ‘take a private vote’ where they press either ‘a red or blue button’.

Viral posts read: “If more than 50% of people press the blue button, everyone survives. If fewer than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?”

While some people think the choice is pretty obvious, not everyone agrees on what that actually is.

So, the idea of pressing red seems like an easy one – if more pick blue, you survive anyway and if not, you still survive.

In game theory, this basic self-interest choice leads to what is referred to as the Nash equilibrium – the best choice for someone looking to advance their own interests.

However, a whole load of users across social media and on polls are picking blue.

“I’m still picking blue and no, you’re not stupid if you pick blue. It’s easier for 50% of people to pick blue than 100% people to pick re. I don’t care about myself and want as many people to live as possible so I’m picking blue,” one user wrote.

And another said: “The downside of pressing the red button is you’ll be left in a world with only red button pressers.”

Everyone in the world has to take a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?

Arguably, picking blue is a ‘gratuitous suicide’ as a red picker suggests: “You are NOT saving everyone. You’re saving people who chose blue. The red button people were never in danger to begin with.”

Either way, the debate has opened up a whole wider conversation about the ‘why’ behind the choice – a quick moral apocalypse for social media as people crash out over whether they’d attempt to save others or save themselves.

Or, they don’t want people to know they’d vote red.

And surprisingly, some polls have absolutely dominated with blue voters.

“The correct answer is always red. If you press red, you always survive. Also, if everyone presses red, everyone survives. Those who didn’t realize this and pressed blue get culled,” one wrote while another joked: “I pressed blue because I know how humans work and I knew that it would have over 50 percent.”

Well, LADs, red or blue?
