HR researchers usually conduct their research using scales, which is a collection of survey items. For example, Professor Headrick is interested in the relationship between work stress and job performance. She measured work stress with 3 survey items and measured job performance with 4 survey items among a sample of workers in an organization. Now Professor Headrick wants to check if the work stress variable has good quality. Which of the following statements about variable quality is FALSE? 1. If the job performance scale is valid, workers' score on this scale should effectively predict their actual performance in the company. 2. An item such as "I am satisfied with my job" may not be a valid item for the measurement of job performance. 3. A reliable scale is also always a valid scale. 4. If the 3 items measuring work stress read similar in their contents (e.g., "My work stresses me out," "I experience a lot of stress in my work," and "Working in this company is very demanding to me"), it is very possible that the scale has high internal consistency reliability
