1. Why is it tempting to use social media platforms for experiments like these? Even

though users of Facebook (implicitly) agree with the conditions of use of the web-site,

which allows this kind of experimentation, is it ethical to do so?

2. Can you think of situations where this type of experiment (or manipulation, if you

like) is justified?

3. How could the emotions or opinions of users of social media platforms (or any other

website) be influenced for purposes which you think are undesirable and/or unethical?

Can you think of possible examples?
