The study conducted by Patrick Bernhagen and Richard van der Vorst deepens the discussion on the political biases of journalists and their impact on journalistic quality. Focusing on a wide sample of journalists from Germany, Switzerland, and Austria, the researchers found that left-leaning ideological views commonly held by the media do not necessarily lead to biased reporting. Instead, these views can result in objective and accurate reporting that often aligns with traditional right-wing standards of discipline and verification. This implies a nuanced relationship between personal beliefs of journalists and their professional outputs.

The analysis by Mark Codington and Seth Lewis further clarifies that left-leaning journalists often feel a strong intrinsic motivation to act as watchdogs against power and institutions. However, this intent to hold powers accountable conflicts with the "firewall" of professional standards within newsrooms. As a result, journalists are compelled to adhere to strict standards of accuracy and attribution, which can sometimes curtail their ideological biases in reporting. This phenomenon reveals the complex dynamics between personal convictions and institutional discipline in the news industry.

This study invites a reconsideration of the stereotype that journalists with political biases produce partisan content, suggesting instead that the commitment to journalistic standards can transcend personal ideological beliefs. The implications of these findings are significant for understanding media credibility and the factors that shape quality journalism in the context of political biases.
