Facebook has a new process for discussing ethics. But is it ethical?

How does Facebook translate broad ethical values into its decision-making process for research?

When Facebook was revealed to have been experimenting on the emotional state of 700,000 of its users back in June 2014, many were outraged that the company had violated ethical guidelines and "harmed" its users.

The fallout of that "emotional contagion study" haunts Facebook's reputation among ethicists and researchers. But it has also compelled the company to clean up its ethical act, and inspired the introduction of a newly developed internal ethics review process this week.
