Andries Sanders
Hello Koppelstok. Thank you for contributing to the article on Andries Sanders. Your edits on his research are valuable since the article did not include any information on that topic yet. However, they need more information to be verifiable, please see Verifiability for the Wikipedia policy on verifiability. I see that you refer to Acta Psychologica, so specific articles names, authors and publication information should be available to back-up the claims now made in the article. I hope you are willing to add them.

I have undone all your edits regarding his life and career since they removed references and sourced content from the article while at the same time introducing text that is not backed up by the sources. Crispulop (talk) 14:21, 25 October 2020 (UTC)
