I've never heard of a department researching a topic that usually comes down to "me boss, you not"; these cool guys wear it so we should too; someone spent significant time under the relevant chief's desk to get what they want; or we've worn this since 1890 and we will continue until hell freezes over.
Good luck, man, but I'd start working on your "there is no data" speech.
