experiments‚ it is less likely that demand characteristics will affect participant’s behaviour. Most participants are not aware they are involved in an experiment and as a result will not be aware of its purpose. On the other hand‚ because many variables cannot be controlled‚ it is difficult to replicate field experiments precisely. For example it would not be possible to replicate the same test at a tube station as people are constantly travelling. Furthermore from ethical standpoint‚ participants

The results indicate that there were certain extraneous variables that were not controlled.
