If police interrogations use leading questions with eyewitnesses or suspects, suggestibility could result in incorrect identifications or unreliable confessions.
For example, if investigators ask witnesses a leading question about a crime, such as, " What colour coat was he wearing? " their memories may adapt to incorporate the suggestions.
And the best research on this has been done by Elizabeth Loftus who has done a series of studies, some discussed in the textbook, showing how people's memories can be swayed by leading questions.
" So I'll be on my own in the house over the pub." She was going to ask him in jest if he could cook but realized that it might sound like a leading question.
