Outdated Scientific Studies Can Perpetuate for Years

Scientific research can sometimes suffer from a form of path dependence where a single study can be cited repeatedly for many years even when it is found out to be incorrect. For example, in 2015 a literature review found that 900 peer-reviewed studies used a cell line derived from a breast cancer patient in 1976 that was found to actually be skin cancer. For eight years (and maybe more) studies kept citing it even though it was incorrect.
