There is no mystery on why left handers are rare.
With the left hand shielding the liver side, the right hand becomes the weapon bearer.
With the left side protexted, the deaths by liver puncture is greatly diminished.
This is called survivorship bias.

- rhcom2 2y agoA fun history fact: > The stair spirals counter-clockwise and is known as the "left-handed staircase" as it would put right-handed attackers at a disadvantage. The story is that in 1513 when the left-handed Sir Andrew Kerr came back from the Battle of Flodden, he had his men learn to use their left hands when swordfighting. In Scotland, left-handedness has been dubbed "Corrie-fisted" or "Kerr-handed". https://en.wikipedia.org/wiki/Ferniehirst_Castle https://en.wikipedia.org/wiki/Ferniehirst_Castle

- gitaarik 2y agoAlso the stomach is on the other side, so if the pointy stick wouldn't puncture the liver, it would puncture the stomach.
- egberts1 2y agoStomach puncture is far more survivable than a liver tear; far far more likely to survive.
- pclmulqdq 2y agoThe spleen is on the left though, and that is an organ that is far more vulnerable and where a rupture is lethal without surgical treatment. I still think this is bullshit, but that would be the organ to choose.
- yencabulator 2y agoSpleen is tiny compared to liver. It's nowhere near as viable as a target. 200g vs 1.5kg.
- jl6 2y agoThe heart is slightly on the left though. This paper takes the "fighting hypothesis" seriously: https://www.mdpi.com/2073-8994/15/4/940 https://www.mdpi.com/2073-8994/15/4/940
- hollerith 2y agoYou are using "survivorship bias" incorrectly: if it doesn't lead someone to an incorrect conclusion, then it is not survivorship bias. What you describe is a selection pressure for right-handedness.
