exam 2 principles of law
when you act differently because you are being watched
observer bias
through experience it can lead to interpretation; if something happened to someone personally, it is going to affect how they interpret data; acting differently because you know you are being watched
observer effect
drawing conclusions to confirm their beliefs (ex. thinking someone committed the crime because they didn't cry when questioned); makes you feel superior; can happen if you get too much context about a case as a forensic scientist; conclusions drawn to support own belief
confirmation bias
"the process of placing an object in a unit category that consists of a single unit. Individualization implies uniqueness." Individualization refers to "absolute specificity and absolute identification." on page 205 of paper 5
individualization
reliance on emotion and cross linkages to draw conclusions (mental shortcut)
peripheral processing
reliance on data to draw conclusions
central processing
error rate associated within lab itself; always disclose that for your lab, these are the results (lawyer may try to discredit your response by saying how does your statement apply to other labs); error rate or variability within an experiment (published development study)
internal validation
error rate in general among all labs; error rate within a real a world problem (applying study)
external validation
prior experience makes you make mental shortcuts, application of things
anchoring effect
gives insight to a case but does not individualize; most evidence is circumstantial; enough circumstantial evidence can lead to juries drawing conclusions; in conjunction with other evidence ties someone to the scene
circumstantial evidence
A jury composed of educated people trained to avoid implicit bias, educated to be a juror
Blue Ribbon Jury
can ask questions; Decides whether there is probable cause to charge someone with a crime (issue an indictment).
grand jury
science can be taken the wrong way if you say it too inflexible; do not box yourself in; allow for interpretation
science is truth
federal standard for evidence admissibility established in 1993
Daubert
judge is gatekeeper and has the discretion whether evidence fulfills Daubert (1996)
kumho Tire vs Carmichael
can give opinions
consulting, expert, testimonial witness
can give facts relevant to the case
fact or material witness
interpretation of the law depends on location and scale of community engaged NOT SOCIETY
legal resolution
following law exactly how its written
verbatim law
interpreting law for a more modern interpretation
interpretative law
evidence that can be traced back to a single source
individualizing evidence
high courts must defer to lower courts for decisions
GE vs Joiner
Thomas coon; huge shift in how things are done but it is based on previous data generated (ex. PMI vs TOC)
paradigm shift
witness can render an opinion
expert witness
low variance in response
precision
disconnect between historical and current data resulting in a novel idea with no linkage to the past
revolution
Federal standard for admissibility of evidence established in 1920s
frye
witness possessing information going to facts that impact case merit
fact witness
process for determining admissibility of evidence of expert for trial - typically done in the presence of a judge
voir dire
rules developed by federal government regulating witnesses and how they are admitted

relevant
witness can render an opinion
testimonial witness
drug presumably responsible for birth defects- resulted in Supreme Court ruling govern evidence admissibility
Bendectin
witness possessing information going to facts that impact case merit
Material witness
data have variance but often capture true result
accuracy
Producer of drug that led to Daubert decision
Dow pharmaceutical
law is interpreted and changes with society NOT LOCATION (interpretation changes over time as society evolves)
living document
Testable, published, error rate, specific community acceptance
Criteria for Daubert
Starts with a general principle and applies it to reach a specific conclusion; "top-down"; uses a general principle or premise as grounds to draw specific conclusions
deductive reasoning
moves from specific observations to a general conclusion; "bottom-up"; uses specific and limited observations to draw general conclusions that can be applied more widely
inductive reasoning
someone that gets hired by an attorney
hired gun
descriptions/categorical information
qualitative
a number value
quantitative
there is no basis on their findings
junk science
develop a hypothesis then analyze data which avoids bias
A priori (priority=hypothesis first)
develop hypothesis after collecting data
A posteriori (post= after experiment)
