Studies that yield positive results are more likely to be submitted for publication than studies that yield negative results due to various reasons such as researcher bias, the pressure to obtain positive findings for career advancement, and the perception of negative results being less significant or interesting. Additionally, scientific journals also have a preference for publishing positive results as they are perceived as being more impactful and attracting more attention from the scientific community and general media.
