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.
Frankly, I hear so much of this "oh that'll never do anything and it just makes people disillusioned" nonsense about ALL levels of engagement ("protesters are hurting their own cause!" "it's just a staffer who reads your letter!" "no one cares what you say!") that I'm extremely skeptical of all such claims.
Maybe rather than tell people who engage that they're failing it would be more useful to encourage them to succeed more.
But there are examples of those types of protests working. Have the petitions ever done anything (other than the death star one which gave the gov't some PR points)?
The activism that happened last year with SOPA actually took effort & targeted the people who were able to act on it. Right now, the petition site seems to be handled exclusively by the White House's PR team.
