>Specifically, after explaining briefly that I was the editor of a tech news site, I would ask iPhone users “why do you use an iPhone?” and Android phone users “why do you use an Android phone?” My phone was always in my pocket when I asked, and I made sure to never mention a rival platform at all.
In about three months I ended up asking 219 different people this question, including 112 iPhone users and 107 Android users. I wasn’t terribly concerned with the features of each platform that people liked most. I just wanted to see how many people, unprovoked, would mention a rival platform in a negative way when offering their responses to a complete stranger.
