I guess I am not human, then.

I'd lie to pollsters because I dislike the practice. It causes irrelevant news, and feeds into strategic voting. One distracts / causes pageviews, other one lowers the integrity of our democracy. My data can skew the accuracy of pollsters, however little that is, thereby hurting their interests.

I am also open to lying to telemarketers as I despise their job. Perfect example of a Bullshit Job.
