Not sure if this should go in GQ or GD, but let’s start it here.
I was just engaged in an argument with some coworkers during lunch. They were pretty insistant that if you receive an organ donation from someone who likes, say, spicy food, then you will soon learn to like spicy food.
Their arguments were largely anecdotal. The most rational person in the room swore that after her father got a near-complete blood transfusion, he was a different person. With completely different tastes in diet.
My argument is that likes and dislikes are not genetic, and further, the donated DNA you get is not going to overpower your current DNA. Any coincidences that arise are purely confirmational bias and wishful thinking.
Who is right?
