Question

Identify three broad categories of types of investigative failures.

Answer 1

Three broad categories of investigative failures are:

1. Cognitive biases

2. Organizational traps

3. Errors in probabilities

Explanation - Investigation done by police-officers depends largely on the identification of guilty by DNA matching which is subject to human error. In addition to this several organizational traps like groupthink, rumour and ego exists. Cognitive bias is the tendency of people to perceive information based on their own experiences and preferences, resulting in a distortion in the judgement of situation or decision taken.
