Random assignments in experiments are important primarily because **they eliminate the possibility of a lurking variable affecting the experiment**. By randomly assigning subjects to different groups, researchers can help ensure that any differences observed in the outcomes are due to the treatment or intervention being tested, rather than pre-existing differences among the groups. This helps enhance the validity of the experimental results.
