Final answer:
The question inquires about the percentage of employers not hiring candidates due to social media. No direct statistic is given but background info indicates social media's strong influence on professional and societal views which can impact hiring decisions.
Step-by-step explanation:
The question is about the percentage of employers who have decided not to hire a candidate based on their social media presence. While no specific statistics are provided directly answering this inquiry, the provided information suggests a broader context where social media usage has significant impacts on societal and professional perceptions.
Specifically, the negative perception of social media's effect on society (64%), the pervasive use of social media (73% of adults engaging in social networking online), and examples of how social media has affected political campaigns suggest that what a candidate shares online can indeed influence the decisions of potential employers.
Furthermore, social media platforms like LinkedIn have revolutionized job seeking and have also become a space where employers and candidates can interact directly. This underscores the importance of how candidates represent themselves through their online presence.
