When it comes to criminal profiling, we need to have a working understanding of what inferences are and how they are developed. Inferences are conclusions made solely based on evidence and reasoning, which is quite different than gut feelings and speculation. Speculation is a conclusion based on guesswork or the belief of answers, despite not having any actual evidence. In order for our inferences to be legitimate, we need to use the scientific method. Remember that pesky method we needed to rehearse and remember throughout grade school? Well, it’s back and it is important in criminal profiling.While we use firm evidence to come to our conclusions, it is imperative that we realize that sometimes we may be wrong. More than that, we need to acknowledge that due to our own life circumstances and experiences may lead us to have our own biases.
