4. Filtering information, filling in gaps, and applying previous knowledge to new situations are all useful traits, even if they do interfere sometimes.Understanding our limitations helps us improve our observational skills.Criminal investigations depend on the observations of all parties involved—police, forensic scientists, and witnesses.
