I wonder if experiments have been done on this. Limit it to the actions of doing nothing, of clicking/signing a petition, and writing a representative. So, the question is if the likelihood of someone writing a representative is increased or decreased by the presence of an opportunity to click/sign a petition. Sounds like the hypothesis here is that the satisfaction of signing a petition would reduce the odds of writing a representative, more than increase it. I could see it the other way though - maybe the civic engagement of caring enough to sign a petition would make it more likely that they'd contact a representative than they would have otherwise. I wonder how the experiment could be structured? Maybe an educational/awareness web page, with a second step of an opportunity to contact a representative, while inserting the "sign-a-petition?" step in between? There are some ecommerce people that believe that by giving buyers more-and-smaller steps to click through, it increases conversion, so who knows.
