Bufale Spotting, part 6: Assessing a lecture


Listen carefully to what is said. After the lecture do a random check on some the evidence presented to sustain a view. Honest lecturers should represent evidence fairly, only giving their opinion at the end (very much like an original paper). If you think the lecturer is twisting the evidence to suit his purpose, challenge him. Either way, be wary of the lecturer in future. Beware of amateurs who clearly have not rehearsed their presentations or who use their position and prestige to ram home a message. Here too, beware of immaculate presentations, especially if they have lots of special effects (sound, music, film clips, logos etc). Big pharma has taken to providing speakers at ‘key’ conferences with ready-made presentations. Quality is very high. The message is commercial.commercial.


Use the same technique as assessing a website.
