Evolutionary Psychology Workshop 5: Partner-Wanted Ad’s.

1. Evolutionary Psychology Workshop 5:Partner-Wanted Ad’s.

2. Learning Outcomes. • 1. Review the evidence concerning the use of lonely-heart personal advertisements (LHPA’s) to understand human mate preferences. • 2. Carry out a content analysis of lonely-heart advertisements. • 3. Discuss the findings in light of theoretical predictions.

3. Background. • Lonely-hearts personal advertisements (LHPA's) are a highly popular means of meeting potential short- or long-term mating partners. • Around 80% of major newspapers and magazines surveyed ran LHPA's (Thiessen et al., 1993). • There are problems in that submitters of LHPA's may represent a biased sample, or that the information provided may be inaccurate (Wiederman, 1993). • However, according to Thiessen et al., (1993) and Greenless & Mcgrew (1994) LHPA's provide an ecologically valid dating and mating arena in which to analyse human reproductive strategies and mate preferences.

4. Advantages of Content Analysis of LHPA’s. • 1. Use of LHPA's is common, and those who place a LHPA do so for valid interpersonal reasons and not just because they want to be volunteers in research. • 2. The placing of a LHPA is a 'real-life' act with genuine consequences and so is akin to a naturalistic observation rather than a controlled laboratory study. • 3. LHPA users offer a broader range of age, class, and experiences than do most studies on mate preferences, which rely on undergraduate students. • 4. The commodities of exchange are clear - both sexes provide information about themselves and their preferences. • 5. The success or failure of a strategy can be followed-up. • 6. The technique is simple to conduct and evaluate.

5. General Predictions. • Based on sexual selection / parental investment we could argue that females may seek males who demonstrate their ability and willingness to contribute to a relationship or on their genetic quality. • Males place a higher emphasis on female fertility and could thus be predicted to seek information concerning youth, attractiveness, parental skills, and fertility.

6. Female Predictions. • We might expect females to offer: • Youth and attractiveness ('cute', 'buxom' 'petite', 'shapely'), caring behaviour ('kind', 'gentle', 'sincere'), perhaps the promise of sex ('cuddly', 'sensual' 'into fun times'). • They may seek: • Resources, and the willingness to invest them (i.e. 'homeowner', 'employed', 'professional' 'generous', 'sharing' etc). • Intelligence ('educated'), mate reliability ('honesty'), and a partner who is older than themselves ('mature'). • Certain physical features (i.e. 'tall', 'muscular') but may not particularly emphasise 'good looks'.

7. Male Predictions. • We might expect males to principally offer: • Resources (i.e. status, job description, property ownership, likes holidays abroad) and reliability ('honest', 'mature' etc). • While they may not offer good looks they may emphasise their height or physique ('tall', 'rugged', 'healthy'). • They will seek: • Younger attractive partners and will probably not demand intelligence, social status, or resources. • Certain characteristics such as 'generosity', 'good sense of humour', 'kindness', 'caring nature' etc may be sought by both sexes.

8. Previous Content-Analysis Studies. • In an analysis of more than 1000 LHPA's, Wiederman (1993) reported than female advertisers sought resources 11 times more often than males. • Males were likely to offer resources and the willingness to invest them (e.g. ‘homeowner’, ‘employed’ ‘educated’, ‘generous nature’) than women. • Males who mentioned resources were significantly more likely to receive a reply. • Thiessen et al., (1993) also reported that males were significantly more likely to offer resources, while women were more likely to seek them. • Greenless & Mcgrew (1993) reported that males sought youth, attractiveness, and sexual availability, while women sought evidence of resources, financial security, and possible long-term commitment.

9. Resource Offering and Requests. From Thiessen et al., 1993, p216.

10. The Factor of Age. • In a review of age preferences, Kenrick & Keefe (1992) found that females typically preferred males who were around 5-10 years older than themselves, and this remained fairly consistent over the life span. • Greenless & McGrew (1994) reported that the average age of male advertisers was 36 as opposed to 34.9 for women and women are significantly more likely to stipulate the age of their preferred partner (older than themselves). • In around 900 LHPA's from the 'Observer' newspaper Pawlowski & Dunbar (1999) found that women typically prefer males 2-3 years older than themselves and this remains stable across the age range, males however request increasingly younger partners as they age.

11. Age Preferences. Data from Kenrick & Keefe, 1993, p80.

12. Age Preferences continued. Data from Pawlowski & Dunbar, 1999, in Barrett et al., (2002) p100.

13. Characteristics of the Sender. • Waynforth & Dunbar (1995) showed that individual preferences are contingent upon what the person has to offer. In more than 800 LHPA's they found: • Women become less demanding as they get older (as their reproductive value declines). • Males become more demanding as they get older (resources increase). • Women offering attractiveness are more demanding. • Males offering resources are more demanding. • Males with fewer resources offer family commitment. • Males and females with dependant offspring make lower demands. • Individuals from higher socio-economic groups make higher demands than those from lower groups.

14. Successful LHPA's. • Lynn & Shurgot (1984) found that females describing themselves as 'slim' received more replies. • Tall, males with dark hair received more replies than shorter males with lighter hair. • Green et al., (1984) compared the most ‘popular’ male and female 'dates' with the most 'unpopular’ from a video dating agency. • Younger and more attractive females were most popular as were older males with high status. • Rajecki et al., (1991) reported that in general women received more replies than men, with younger women and older males receiving the most replies.

15. Pawlowski & Koziel (2002) • Using matrimonial bureau records of 551 male and 617 female LHPA's they analysed which particular stated traits influenced the 'hit rate'. • As in previous studies males offered resources and sought attractiveness, while females offered attractiveness and sought resources/commitment. • For males the most important predictors of hit rate (in order of success) were education, age (older), height (tall) and marital status (single) and resources. • For females the most important factors influencing hit rate were as follows: weight (thin), height (medium), and education (less). • Surprisingly attractiveness offered was not a significant predictor.

16. Activities. • 1. Use the table provided to put together a tally sheet of features offered and requested by each sex. • We will collect the data together and discuss the findings. • 2. Using your knowledge concerning successful LHPA's, write an LHPA for a male and female that you think should bring them success.
