Study 1: Confederates asked one group of participants to read temperature and another to read air pressure. Regardless of whether the participants complied with the first request, they were given a second one. One group read temperature first and the other air pressure. Results show that participants were more likely to agree to the second request following the first than the second request in isolation, regardless of whether it was to read the temperature or air pressure. There were participants who complied with both requests, but there were also participants who complied to the second, but not the first request.
