The dilemma of two button

A small mental experiment. Let's imagine that every person on the planet who is able to make decisions at one moment found himself in a locked room with two buttons. Blue and red. To exit, you must press one of the buttons. Clicking on the buttons leads to the following actions: 1) If the majority of people (at least 50.1%) participating in this experiment choose the blue button, then everything will remain as it was, people will disperse and continue to live their lives as if nothing had happened. 2) If most people choose the red button, then everyone who chooses the red button will remain alive, and everyone who chooses the blue button will die. You don't have the opportunity to communicate with other people and come up with a common solution. You don't know how the majority will vote. Which button will you choose?
