The document presents a research proposal that aims to determine which type of pickup line is most effective in face-to-face contexts between males and females. The three types of pickup lines that will be tested are direct, innocuous, and flippant lines. The effectiveness will be measured by participants' willingness to provide their phone numbers. Both male and female participants will receive each type of pickup line from a researcher of both genders. The results will then be analyzed to conclude which style of pickup line works best. Ethical considerations like obtaining consent and allowing withdrawal are also addressed.
