An article in a psychological journal reported, "The reliability of the personality ratings was .55.  The reliability of the supervisor's ratings on the job was .48.  Personality ratings correlated with the measure of job success to the extent of .65."  Why should you automatically suspect that there was an error in the report?
A) The correlation between two tests cannot be higher than the reliability of the more reliable test.
B) A personality rating could not be more reliable than a measure of job success.
C) It would be very rare to obtain a validity coefficient this high.
D) The correlation clearly has not been corrected for attenuation.
E) It would be unusual to have the reliability of ratings be this low.
