Wikipedia's own article on Henry Sidgwick, the Cambridge philosopher and co-founder of the Society for Psychical Research, is a tertiary encyclopedic source. Its strength is that it reliably records his standard biographical and career facts. Its limit is the ordinary one for a crowd edited encyclopedia entry: fine for uncontroversial biographical detail, not a substitute for specialist scholarship on his philosophical or psychical research work.

Reliability Tier3
Reliability tier 3: a Wikipedia entry, written and revised by unnamed volunteer editors, suited to uncontroversial standard biographical fact rather than to specialist scholarship on his philosophical or psychical research work. NotesWikipedia's article on Henry Sidgwick. A perpetually community-edited reference page rather than a peer-reviewed publication; use for standard, uncontroversial facts about Henry Sidgwick (biographical detail, dates, common definitions), not as the source for a contested or specialist scholarly claim.
