Wikipedia talk:Defining

Applying defining example
I have just applied Category:Words coined in the 1990s to Talent management. Is this defining? Ottawahitech (talk) 11:19, 16 October 2015 (UTC) please ping me

Li Ka-shing
I have just added Category:Hong Kong chairpersons of corporations to Li Ka-shing. Is this a defining characteristic of this individual? Ottawahitech (talk) 14:59, 31 October 2015 (UTC)

Source of the rule
Where did this rule about "definingness" of categories originate? Was there broad consensus or was it a close call? It is much more restrictive than in other language versions of Wikipedia, and has drawbacks, though I understand the aim of avoiding overcategorization. Could anyone provide a link to the deliberation which produced this criterion? Baronnet (talk) 15:52, 31 March 2023 (UTC)
