Tempered is a working method for the people whose names go on the result: leaders, consultants, lawyers, analysts, regulators, accountants, managers, and anyone who has to answer personally for what they send. It is not a theory of AI. It is a procedure for the moment you sign. The method is shown working with three jobs you already do: summarising a set of documents, reviewing a contract, and writing a more complex document. Each runs at full speed, with the checking built in. Part I of the book makes the case. Part II is the practice. You will learn how to: > look for the failures that leave no trace on the page, from invented citations to work that reads well but is wrong; > place a small number of real checks where being wrong would cost you, and stop relying on pretend checks everywhere else; > keep a record that shows where the work came from and who decided what; > say clearly and openly how the work was made, and handle that disclosure so it reads as real command of your work rather than an apology for it. > Use AI at full speed. Run the checks that matter. Put your name on the result, and know what you are standing behind.
