People often mix up prejudicial effect with probative value. Probative value is how much a piece of evidence actually helps prove a fact. Prejudicial effect is the risk that the same evidence will push a judge or jury toward an unfair decision based on emotion, bias, or distraction instead of the real issues.

Not all prejudice is a problem. Evidence can hurt one side and still be allowed if it is genuinely useful. The real concern is unfair prejudice - for example, graphic injury photos, prior bad acts, or inflammatory comments that may cause people to react emotionally rather than weigh the facts. In Delaware, this comes up under Delaware Rule of Evidence 403, which allows relevant evidence to be excluded if its probative value is substantially outweighed by dangers like unfair prejudice, confusion, or misleading the jury.

For an injury claim, this matters when deciding what records, photos, videos, and testimony to use. If evidence is vivid but only weakly connected to what happened, the other side may try to keep it out. On the other hand, clean, well-documented medical records, treatment notes, and practical proof of pain, limitations, and recovery usually carry strong value without the same risk.

What to do: keep documentation accurate, dated, and tied to the injury. Avoid exaggeration. In a Delaware case, especially after a heavy-traffic crash in New Castle County, evidence that is clear and medically grounded usually holds up better than evidence that only creates heat.
