Developing and bringing a new drug to market is an intricate journey that involves rigorous testing, meticulous research, and, crucially, the scrutiny of the scientific community through the peer review process.

However, the system has flaws, and one of the most insidious threats is the presence of biased medical peer reviewers.

The Peer Review Process:

In medical research and drug development, peer review plays a pivotal role in determining whether a new drug is safe, effective, and worthy of regulatory approval.

In that case, there may be a subconscious inclination to favor certain products over others, influencing the review process.
