# 46. Logical Manipulation ## 46.5. Methodology/Refinements/Sub-species ### 46.5.4. Ignoring a common cause Claiming that one event caused another, when a third (unlooked for) event is probably the cause. Example: "We had the 60s sexual revolution and now people are dying from Aids." The manipulator is delivering a moralising payload, ignoring the fact that the 60s also brought a huge increase in international travel, human population, development of forest areas of Africa, etc. These were the real contributory factors in the development and spread of Aids, with the sexual revolution in the Western world being largely irrelevant in terms of HIV.
