Sorry for the crude title but there wasn’t enough room to type “overweight/unattractive vs. svelte/attractive”
Anyway, lets assume that each girl is equally pro-choice, unsure about the longterm stability of the relationship with the father and not at a point in their life where they are ready/wanting to have a child.
I'm saying that the overweight female is less likely to get an abortion based on these thoughts. By being pregnant/having a child the overweight woman has a symbol and or proof to the world that she is sexually active and desirable, an issue that some (but not all) overweight women might have to deal with, sort of a social-sexual validation type thing. The overweight woman might also assume that her chances of finding a mate to have a child with in the future (when she does want one) might be very low so she should keep the one she has the potential to have now.
The attractive female in the same situation is more likely to get an abortion based on these thoughts. She may be afraid of diminishing her attractiveness and missing out on the many years of attention and compliments and then possibly losing out on snagging her alpha male of choice in the future (that she would want to have children with) due to the fact that she isn't as pretty and is now with child.
Your thoughts?
