What does that have to do with anything?
I think you are just avoiding the question, about testing what indicators in a browser that are the most (and least) helpful to users.
As a browser vendor, I expect you to welcome research that helps you design your browser in such a way that it help as many users as possible to make the best security decisions in every situation. If you find the available research unreliable, do your own tests, and publish the report, with method and results and all (trust through transparency).
As a CA, on the other hand, I understand that you welcome some results more than others. CAs, of course, want their products, the certificates, to be as visible as possible in the browser. Not least EV, the currently most visible (and expensive) type of certificate. If the indicator goes away, it will be very hard to sell EV-certificates.
