Introduction
• Forensic psych is an applied course, how we apply research and information to the legal
system.
• We see this is the media, we experience before we learn about it, we get it from movies
and television.
• Begiig i the earl 90’s people eae failiar with foresis through profilig.
• Profiling has been depicted very erroneously, it is seen as something you cannot teach,
you are born a profiler, some people have this intuitive skill to understand the kind of
criminals.
• This view is still predominant today.
• Criminal minds is relatively accurate, it depicts the activities in the BAU, which is the
most dominant source of profiling.
• In criminal minds they always get the right guy, this is not the case for actual profiling.
• Paul Eka is the world’s leadig epert o the faial epressio of eotio.
• He has talked about micro expressions, quick fleeting expression of emotion that are
different from what the person is saying and how they feel you carefully examine a
person you can detect these micro expressions.
• CSI is about forensic science in a lab, it is interesting however it does not tell the full
truth, a number of tests they perform are not as reliable as we might think, there is an
error rate.
• People who actually worked were always jealous because they had all the best
equipment, they also got their result back within hours, they over simplify it.
• Everything they pick up is relevant to the murder, they make it seem so simple, it is very
hard work.
• The CSI effect, jurors believe distrust cases that do not involve forensic evidence
because of these shows, they think every case needs forensic evidence, they raise the
expectations of what jurors expect to see.

• Chemistry analysis of substances on and around the crime scene.
• Forensic engineering, how did the fire happen or bridge collapse.
• Lots of forensic medicine.
• Looking at pathology, dentistry and toxicology.
• There is even meteorology, what was the weather like, how does this effect the crime.
• Accounting, they bring this person in whenever there is a money crime like fraud etc.
• Many of these things have been applied to the legal system making them forensic.
Forensic evidence
• There is a belief that a good case must involve forensic evidence.
• The truth is less than 20% of all criminal trials involve forensic evidence, in fact only 10%
include forensic evidence.
• Most criminal cases do not involve forensic evidence.
• Only 45-59% of forensic evidence is actually analyzed.
• Most labs do not have the equipment to analyze all of that data.
• The media makes us think that it is a big deal, but it is not a big deal, most of it is
inaccurate, there is a high error rate for these comparisons, this is not science it is exert
comparison, experts make mistakes
• In 1959 Biasotti looked at error rates when dealing with bullet comparisons.
• The average percent match has a 70% error rate when fired from the same gun.
• 15% error rate with 2 different guns, this really can hurt a trial.
• there is a high error rate matching body evidence, there are high biases.
• Every single form of forensic evidence has turned out to be much less reliable than
anyone though including finger prints.

Document Summary
Introduction: forensic psych is an applied course, how we apply research and information to the legal system. Cognitive interview: asking the person to reimagine the situation they were in, reinstate the original context. Imagine what it would look like if you were not standing where they said: the problem here is that you may be eliciting false memories or inferences that did not actually happen. It is a more detailed recall but overall they are more inaccurate, they make more errors. sexually abused by their fathers, these therapy sessions were very suggestive and the women began to think it was true. If this goes well you may identify a few people you think are guilty: part 3 now you have an accusatory interview if they seemed guilty. In the reid method you may use either or both. Less sure of the interrogations objectives and did not realize how much information they gave up.
