Clark & Hatfield

  • males and females approached strangers of the opposite sex 
  • based on a uni campus with students 
  • they asked the strangers 3 questions:

- will you go out with me tonight 

- will you come back to my house with me 

- will you have sex with me 

  • 50% of men and women agreed to going out that night 
  • no women agreed to sex but 75% of men did

Clark & Hatfield AO2

- the campus may be a situational variable

- social desireability effect - if the people being asked are with friends they may gave different asnwers to what they would if they were on their own 

- there is low mindane realism as the experiment has been made to seem artifical 

- it can't be fully generalised as it only uses students 

- there is low internal validity as it isn't a controlled experiment 

- the findings may be artefact of the research situation 

- it is very reliable as it can easily be repeated 

- it supports the findings of Trivers

6 of 7


- there is evidence for the approach in the real world 

- the approach is very deterministic - it negelcts free will and says one thing will determine the behaviour of the other thing 

- it neglects culture - there may be differences between other cultures that aren't western eg collectivist cultures 

- it is less relevant in a contemporary society - most of the research is based in the past eg males may now invest more in their offspring 

- the approach is very sexist 

- it isn't a scientific appraoch
