The question asks the respondent if he agrees with the statement that he would rather suffer himself than have a woman he is in a relationship with suffer. Being openly willing to suffer for a lover is clearly the mark of a beta. If you're engaged in pumping-and-dumping, the girl is in the process of suffering for your pleasure even as the GSS question is being considered. Your answer is obvious.
Responses are on a five point scale, from strongly agreeing to strongly disagreeing. Not surprisingly, a majority of men strongly agree--chivalrous ideals are not dead, and by definition betas outnumber alphas. Where the alpha-beta dividing line among the four other responses is placed is contingent upon what percentage of the total male population is alpha and what percentage is beta. Of course the Game narrative does not maintain that an absolute dichotomy exists, but for empirical purposes distinctions have to be made somewhere.
In his definitive post on what constitutes an alpha, Heartiste puts the low end ("lesser") alpha at 7 on the 0-10 point scale, while Adonis ("greater alpha") is obviously at 10. Since it's actually an 11 point scale, the 0-6 beta and omega range comprises 64% of the population while the 7-10 alpha range comprises the remaining 36%. Separating the "strongly agree" beta response from the other four yields a 69.3%/30.7% split, corresponding very well to the chart included in Heartiste's post.
As Heartiste is one of the Game narrative's intellectual giants, this is how I'll define the alpha/beta split for the purposes of considering differences in fecundity between alphas and betas. The following table shows the mean number of children for alpha and beta males. To avoid racial confounding, only non-Hispanic whites are included. To allow adequate time for procreation to occur, men aged 40-65 are considered. As the question was posed in 2004, it has contemporary relevance:
Betas make more babies than alphas do. This should be warmly received by everyone! From the beta perspective, their chivalrous instincts are out propagating the caddish tendencies of alpha males, which presumably indicates a virtuous cycle of increasing chivalry in the future. From the alpha perspective, this portends a future where the jungle is increasingly populated by inept beta hunters, allowing alphas to poach kittens and cougars with ever greater ease.
Parenthetically, why is so much scorn heaped upon betas by alphas? The basic concept of supply and demand suggests that the relatively fewer alphas there are, the easier their pickings become. Every man may need a harem, but the math doesn't work out for every man to have one!
