1. What are the observations that led to the generation of the above hypotheses? 2. Do both hypotheses make testable predictions? How could you test them?
3. Subsequent experiments, examining several million Ihildren, disproved a link between thimerosal and autism:
in fact no link of any kind was found to exist between vaccination and autism. Dr. Wakefield was found to
have fabricated data, his paper was retracted, and he lost his license to practice medicine in the UK. Does the
falsification of Hypothesis 1 vindicate the supporters of Hypothesis 2?
4. Although thimerosal was found to have no connection to autism, it will removed from most childhood vaccines
duc to public pressure, While this pur many concerned parents at cause, and from this, may have increased the
rate of childhood vaccination, it decreased the shelflife of the vaccinc, making the vaccines more expensive to
produce. Was the removal of thimcrosal a good decision?
