Hi, and welcome to Wikipedia.

You have repeatedly made the same edit to Henri Tajfel. I and another editor have reverted your edits. At this point, you shouldn't just keep repeating the same edit. You should come to Talk:Henri Tajfel, explain your reasoning and seek consensus for a change. See WP:BRD, which explains how and when it is wise to discuss edits. Repeatedly pushing the same edit without discussion is edit-warring and not allowed.

Every edit you've made, you've marked as "minor". Your edits have not been minor. See WP:MINOR for what counts as a minor edit. You have also added new content without providing a reliable source citation. Material on Wikipedia articles has to be verifiable. Your input on how to improve the article will not get a positive reception if you don't follow Wikipedia's basic principles. Bondegezou (talk) 09:43, 12 August 2019 (UTC)Reply

As far as I know there has not been an investigation into Tajfel's behavior. Although I believe these women in the article you cite, their statements constitute allegations. That Tajfel was a Polish Jew, whose family was killed in concentration camps is a historical fact; It is therefore understandable that he was more interested in racial conflicts than in gender conflicts. Also, there is no law that a psychologist should be interested in gender conflicts. Mentioning it in this context is an insinuation.Tajfel PostDoc (talk) 14:46, 12 August 2019 (UTC)Reply
If you wish to discuss the article, I suggest you repeat those points at Talk:Henri Tajfel.
We do not write Wikipedia content based on inferences, however "understandable". If you want to make a point about Tajfel being more interested in racial conflict because of his life experiences, you need a citation saying that. The current text is based on what a citation says. That's what we do on Wikipedia: we follow what reliable sources say. Do you have any sources supporting your thesis? Bondegezou (talk) 17:45, 12 August 2019 (UTC)Reply
