cited several TV shows that featured a "classic war between blonde and brunette love interests", including The Office (where lighter haired Pam Beesly competes with brunette Karen Filipelli for the attention of Jim Halpert), Suits (where blonde Jenny Griffith competes with brunette Rachel Zane for the attention of Mike Ross), and Dexter (where blonde Rita Bennent and brunette Lila West compete for the affections of Dexter Morgan, the main character). Typically, she wrote, "... the blonde (is) stable, and typifies the 'girl next door,' while (the) ... brunette, is haughty, and a bit more exotic." In Archie comics, Betty Cooper and Veronica Lodge have been engaged in a mostly friendly competition for over 70 years. A number of studies have been conducted over the years to measure society's attitude toward blondes and brunettes. Some studies have shown that men, mainly those of Caucasian descent, find blonde women more attractive than brunettes, redheads, or women of other races who had darker hair, eyes, or complexion. Other studies, however, have shown that more men find brunettes more attractive, due to geographic location, familiarity and perceived emotional and cultural connection. A Cornell University study showed that blonde waitresses receive larger tips than brunettes, even when controlling for other variables such as age, breast size, height and weight. In a 2012 interview with NBC News, Lisa Walker, Sociology Department Chair at the University of North Carolina said that hair color "absolutely" plays a role in the way people are treated and claimed that numerous studies had shown that blonde women were paid higher salaries than other women. In a study by Diana J. Kyle and Heike I. M.

In addition, participants designated the female applicant's starting salary as significantly lower when she was depicted as a blonde than when she was shown with brown hair. A study that looked at the CEOs of the Financial Times Stock Exchange's (FTSE) top 500 companies investigated how hair color could be a potential barrier to professional success. In another study by Brian Bates, two sets of MBA graduates were given the same Curriculum vitae of the
