Our minds are incredibly accurate and efficient, but they are not perfect. The thinking errors that we make every day are usually mundane but can be highly consequential in the legal system. Have you ever forgotten a new acquaintance’s face? We all have, and usually with minor consequences, if any. This error becomes problematic in the legal system, though. Eyewitnesses to crimes sometimes make memory mistakes that lead to innocent people being accused and imprisoned of crimes they did not commit. People also sometimes fail to notice missing or wanted people in their midst. Our conversation will focus on these errors and how we can avoid them or account for them in the legal system.
