[2026] PTE Academic Reading - Multiple Choice, Single Answer

The traditional view of forensic science, as popularized by television dramas, suggests that a single piece of evidence—a strand of hair or a smudge of a fingerprint—can provide infallible proof of guilt. However, recent exonerations through DNA testing have revealed that many of these 'gold standard' techniques are based on subjective pattern matching rather than rigorous statistical data. For instance, bite-mark analysis and hair microscopy, once considered definitive, have been largely discredited as unreliable by the broader scientific community. This crisis of reliability stems from the fact that forensic laboratories often operate in isolation from the peer-review culture that defines modern science. While technological advancements are improving the accuracy of certain methods, the judicial system remains slow to adapt to the reality of scientific uncertainty. To ensure the integrity of the courtroom, we must move away from the myth of forensic infallibility and demand a higher threshold of empirical validation. A truly just system recognizes that even the most sophisticated evidence is only as strong as the statistical probability it represents.
