No they are not the same
PSL= A set of rating standards made by individuals in looks theory forums concocted to act as a basis of rating that differentiates from the usual 1-10 scale, centered around the Eurocentric beauty standard.
It is more so used to deduct whether a person fits to a Blackpill-made standard that relies on them looking as humanly perfect as possible, rather than their actual desirability.
Appeal= The sexual market value (SMV), or level of desirability of a person in the current dating and love market. Appeal factors do not only focus in on pure physical looks- social status, economic class, current looks preference and preferences of surrounding individuals are also weighed in.
A high appeal individual does not necessarily have high PSL, and vice versa.
