Answer and Explanation:
A possible source of bias that this question may represent is the use of "Steve Jobs" as the only example. This is because the use of Steve Jobs as an example can lead people to respond that they like the idea of uniforms, taking into account that this practice is associated with Steve Jobs' success in his work. Thus, workers can associate the concept of being successful with the concept of wearing uniforms.
In addition, to avoid bias in the responses, the researcher should have used an example within the work area that the workers work in, allowing them to see the advantages and disadvantages within the reality they live in.
