Job analysis depends on individual's subjective judgments, and may subject to inaccuracy of job information. The aim of this research is to determine which kinds of social and cognitive sources of inaccuracy may affect job information completeness. Such social sources as extremity shifts and social desirability, as well as cognitive sources such as heuristics and categorization may result in job information incompleteness of job analysis.
Laboratory experiment was designed to verify hypotheses, four independent variables mentioned above were manipulated respectively by job analysis forms, instructions of study goal, job information sources and job analyst identity. Setter and main attacker of volle沙all were chosen as the target positions. The subjects involved three categories. The athletes (who were regarded as incumbents) and the coaches (who were regarded as supervisors) came from 16 volleyball teams of –Beijing universities, and job analysts were students majoring in human resource management from 2 universities of Beijing. All subjects counted up to 245. Position Analysis Questionnaire (PAQ) was delivered to collect data.
ANOVA results showed that (a) there was no significant effect in extremity shifts; (b) socially desirable responding could result in incomplete job information, when there was an instruction accentuating the position's value to the organization, and more likely from incumbents than job analysts; (c) there were interactions in heuristics' effect, under instruction of research purpose only coaches were affected, whereas under instruction of determining on position contribution purpose all three sorts of subjects were affected, and heuristics were less likely when job description was provided to athletes, as well as video was showed to job analysts; (d) categorization of jobs could result in incomplete job information, this was more likely when respondent were job analysts, and there was no significant difference between supervisors and incumbents; (e) the effect of social and cognitive sources on job information completeness was modulated by a mediate variable (i.e. job information content).
