Science denial is a problem because it can have serious consequences for individuals and society as a whole. When people reject scientific evidence and consensus, they may make decisions that are not based on factual information, and this can lead to poor outcomes. Moreover, science denial can undermine public trust in scientific institutions and the scientific process, which can have long-term negative effects on society's ability to address challenges and make informed decisions. By rejecting scientific facts, we risk denying ourselves the benefits of scientific progress and innovation, which are crucial for improving the quality of life for all people.
