CSI Effect

CSI effect is the expectation that real criminal cases should produce abundant, fast, high-tech forensic proof because crime television makes that look normal. 121.极简法医鉴识手册：一切犯罪，皆有痕迹 uses the term after discussing CSI-style dramas and the public’s fascination with法医/鉴证 work.

In the source, the effect matters in court and online. Jurors may wonder why there is no DNA evidence, and online audiences may treat partial fragments as enough to judge a person. The episode counters both habits by stressing that labs are expensive, resources vary by jurisdiction, and [[ForensicScience|forensic science]] still has uncertainty even when evidence exists.

Key Claims

• Entertainment can make forensic evidence look more available, cleaner, and more decisive than it is.
• Lack of spectacular evidence is not automatically proof of poor investigation.
• Physical evidence should be valued over unreliable memory, but Evidence Over Testimony is not the same as laboratory fantasy.
• Public judgment needs Rational Humility because real evidence often arrives incomplete, slowly, and with confidence limits.

Connections

• Forensic Science / 法证鉴识 - field distorted by media expectations.
• Modern Criminal Investigation Formation - institutional reality behind lab capacity and procedure.
• Internet Moral Trial / 互联网审判 - online counterpart of overconfident judgment.
• Observation Before Inference - reasoning guardrail against TV-shaped certainty.
