The text reports a 2013 test run where DNA lab workers were asked to study a mixed DNA sample from three people and decide if a suspect’s DNA was in it.
The real answer was NO, the suspect was not part of the sample.
Yet the results were:
70% said the suspect might be included
24% said the result was unclear
Only 6% gave the correct answer
The point of the passage is not about DNA itself, but about human judgment. It shows that when DNA samples are mixed and hard to read, many trained experts can still reach the wrong call or hedge instead of rejecting a match.
