Final answer:
The Seattle study is considered inconclusive due to confounding data, inconsistencies in definition and description of the subject, challenges in empirical measurement, lack of representativeness, and potential bias and faulty reasoning in the study design.
Step-by-step explanation:
Some factors that render the Seattle study inconclusive include confounding data, which means that it's unclear whether improvements in the study were due to the intervention being tested or another factor.
There is also a concern about the way the subject is defined and described, as highlighted by researchers like Locke and Meyer et al. Moreover, inconsistent empirical measurements and difficulties in studying the topic rigorously have been cited as reasons for questioning the reliability of the results.
The validity of the research is further questioned due to potential issues with representativeness of the study participants, which can affect the generalizability of the findings.
Finally, some researchers have pointed out faulty reasoning related to cause and effect, as well as the potential for bias and a lack of objectivity within the study.
