Faced with the problems of insufficient evidence, of conflicting evidence, and of evidence relayed through the flawed perceptual, retentive, and narrative abilities of witnesses, a jury is forced to draw inferences in its attempt to ascertain the truth.
Topic
How juries make inferential errors during trials, and how these errors can be misunderstood or mishandled by courts and judges.
Framework
Problem / Solution
Main Point
Jurors often draw mistaken conclusions from evidence due to predictable cognitive errors, but courts and judges generally have a limited understanding of how and why these errors occur, neglecting insights from cognitive psychology. The "Most Valuable Sentence" is: (last paragraph)
P1: Juries Must Infer—But Sometimes Go Wrong
Juries have to draw inferences from imperfect or incomplete evidence, and although they usually rely on the cognitive tools they've used in everyday life, those same tools can lead to errors when making decisions about the facts in a lawsuit.
P2: Examples of Inferential Errors
Most jury mistakes involve reading too much into evidence—like assuming someone is guilty because they've been convicted before, being swayed by graphic photos, or discounting testimony that's not delivered well. Sometimes, if there's too much or too confusing evidence, juries can even make completely unfounded decisions.
P3: Psychology Explains Why Errors Happen
Research in cognitive psychology shows that people make these kinds of mistakes in predictable ways, depending on the situation and the information available. This research could help courts understand when and why juries are likely to misinterpret evidence.
