I believe P-hacking is unethical because it allows the data that has no basis to be confusing to the ones that have data. Society and media can respond in an up to date way and stop this from happening. For instance media plays a big part when it comes time for collecting the data for the society while societies role is to analyze the topic so that some one can understand and not give the media false information. P-Hacking benefits a researcher and can only give pessimistic effects to society.
