Final answer:
Implementing a mentorship program and encouraging open communication are solutions to prevent the self-fulfilling prophecy in vertical differentiation.
Step-by-step explanation:
To prevent the self-fulfilling prophecy in vertical differentiation, one example of a solution is implementing a mentorship program. This program can provide opportunities for employees to receive guidance and support from more experienced colleagues, helping to break stereotypes and biases about their abilities. Another solution is encouraging open communication within the organization, promoting a culture where employees feel comfortable expressing their ideas and concerns. This fosters a sense of inclusion and reduces the likelihood of biased expectations leading to discriminatory behavior.
