I was once asked to edit a sociology paper for grammar, spelling and style, but ended up deleting large swaths of it containing claims made up of thin air and found nowhere in the data or the citations. Of course this was not well received and I expect every one of those passages were promptly restored, complete with their horrendous spelling and grammar.
The claim? That the biggest challenge facing remote poverty- and alcoholism-stricken communities of indigenous peoples were not enough tablets to be able to "Netflix and chill". Because surely that will solve all the world's problems.
