(Atleast I think) that women and children are saved first during a disaster, Why?
Aside from the obvious chivalry, consider it as an efficiency in division of labour.
Assumed premise: Women, children and elderly, whether due to size, knowledge, or strength have been (at least historically) slower and weaker than men in situations requiring speed and strength and good decision-making (perhapsd merely due to training or previous experience).
Scenario 1 (every man or woman for him- or herself):
1a] Disaster strikes.
1b] All the men rush onto the life boats.
1c] The eoment, children and elderly, make poorer decisions, freeze, act too slowly are are simply incapable of garnering the strength to get to the lifeboats
1d] meanwhile the men stand around on the lifeboat, reading the paper, saying "Look, this boat is leaving in ten minutes whether you're in it or not!" They are wasted as a resource.
This scenario has theoretically
no limit on how long it could take to get everyone in the lifeboats, because the goal is only reached once the
slowest person gets to the finish line.
Scenario 2 (which should be fairly obvious by now):
2a] Disaster strikes.
2b] The men stick around to organize the elderly, women and children, which, indepedent of anything else, will get things moving along.
2c] Any sitution that cannot be handled by a given person (due to strength speed or intelligence) will be taken over by someone who is faster and/or stronger.
2d] The last ones off the boat are the ones most capable of getting off under their own power under worsening conditions.
In this scenario, the time elapsed is minimized.
If you accept the premise, the rest follows automatically.
