Is it permissible to continue working for a company that develops a medical device for early detection of genetic diseases, if my role is limited to technical analyses and informing officials about the lack of accuracy of the results and the weak contribution of the genetic factor, while they insist on marketing the product as an effective means of genetic diagnosis despite their knowledge of its shortcomings?

Since the genetic factor adds only a small percentage to the medical tool's ability to predict the disease, it is not permissible to market it as effective for genetic diagnosis, as this involves lying and deception. As for the questioner's work in technical analyses and objectively sending the results, we do not see any prohibition in it, because it does not assist the company in its marketing deception. The prohibited assistance in sin and transgression is that which is direct or intended. While we do not rule the questioner's work as prohibited, he should alert officials to the lack of accuracy of the results and the insignificance of the genetic factor in the tool's predictive power for the disease, and advise them to be objective and honest in marketing.
