If you evaluate the probability of the appearance of the comet but include in your background evidence the assumption that Newton is correct, then (setting aside the problem this would probably be the fallacy of begging the question) the probability of the 1758 comet would be very highit is, after all, derived from the Newtonian explanation as its outcome! , Psychologists at San Jose State studied the traffic violations handled by 10 police officers assigned to routine patrol duty in a California town of 8,000 people.

The planet is too dim to be seen, but the scientists said they are convinced it is there because the pulsar emits radio signals that vary in a way that can best be explained by the gravitational tug of a nearby planetthe waves are a bit early for three months, then for three months arrive a bit late. Treatment: in a research study, any condition applied to subjects - those in the treatment group - that is not applied to subjects in a control group. The argument concludes with the assertion of the explanation.
