Willful blindness refers to intentionally ignoring facts or information in order to avoid liability for wrongful acts. It is a term used in criminal law where a person fails to be informed of matters that would make them criminally liable. Willful blindness cannot be used as a defense in criminal court, as it makes the defendant criminally liable for their intentional ignorance regarding their actions. An example is a case where a defendant argued their file sharing technology had no way to monitor content, but the court still found them guilty of copyright infringement through willful blindness.
