how would you, as a writer, build goodwill with your readers?

Answer 1

By writing well, credibly and consistently over time.

Answer 2

Objectivity (seeing and noting both sides of every issue)

Credibility (cite sources, especially for numbers)

Readability (mix in a little humour, but mostly write to the level of your reader)

Answer 3

writing sense
