Mrs Ellemers is a professor in social psychology. Her work has been recognised by many awards and the English Wikipedia does report about this correctly. The European Association of Experimental Social Psychology recognised her twice; once with the Kurt Lewin medal and once with the Jos Jaspars Medal.
Recognising people for their achievements is relevant because it indicates how peers appreciate one of their own. It is also a way to establish notability. Like so many topics for credibility sources are important. They are however susceptible to "bit rot". The EAESP changed its website and all the Wikipedia links are dead.
Wikidata knows about these awards as well and, each has a link to the URL for "official website". On it you find all recipients of the award. Mrs Ellemers is good; the new sources provide the needed confirmation.
Awards for a person can be a list generated by Wikidata. Associated sources can be as well. With Wikidata as the source for lists and sources, Wikipedians are free to provide the textual content about a subject and Wikidata would be the place to store sources and lists. In this way information will be maintained in one place and quality for all articles will improve.
