Thanks. Good points. Note that many of those words are already established in the literature with same meaning. For the particular example of "doomed", this is the standard term for this concept, and was introduced by Greenland and Robins (1986). I guess I could instead use "response type 1" but the word doomed will be much more effective at pointing to the correct concept, particularly for people who are familiar with the previous literature.

The only new term I introduce is "flip". I also provide a new definition of effect equality, and it therefore seems correct to use quotation marks in the new definition. Perhaps I should remove the quotation marks for everything else since I am using terms that have previously been introduced.
