UTSA scholars to study health effects of electronic cigarettes The Good: The Bad: The Ugly: I understand the basics of structuring a research project. Usually a negative hypothesis is proposed: "X does not have the effect of Y." Then when little to no evidence is found to support the negative hypothesis, the study provides evidence that "X does have the effect of Y." However, even though the wording of the hypothesis displays a negative attitude toward e-cigarettes, it is not formulated as a negative hypothesis statement. "The scholars will test the hypothesis that inhaling vaporized nicotine does not stimulate the human nervous system in ways that could seriously impact daily living." Also, given the fact that e-cigarettes were never intended to be marketed to the entire population, any testing of this sort should compare the physiological effects of Method A of obtaining nicotine (smoking) to Method B (vaping) to provide the public with a complete picture of the effects of switching from smoking to vaping. So the full hypothesis to be tested would be "inhaling vaporized nicotine has a worse impact on the human nervous system than inhaling smoke."
