1916 US trade-manual practice. Sargent defines heart interest as the quality that excites 'the kindly emotions' and appeals to the heart rather than the head, and says beginners wrongly equate it with love (marriage) interest; no sex-love is needed. His closing paragraph gives it two jobs: the base of a story that appeals to the kindly emotions, and, secondarily, small touches that give reality and naturalness to a forced situation. He says its essence is genuineness and sincerity and that it comes from the writer's personality, yet also that an adept author can train himself to use touches; the two statements sit side by side without reconciliation. His claim that it is 'in constant demand' is an assertion, not data.

Curator qualifications: Heart interest, charm and distinction verified as Sargent definitions, with Chesterton quoted as a third party; unsupported trade assertions are flagged by the producer. The -07 review list is derived from the source and its table procedure is a proposal.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
