I pulled out my phone during a lecture once my professor started talking about a taboo topic - genetic heritability of IQ and other traits such as height and illnesses. I questioned whether or not I should upload it due to the bad phone image and swimming-pool-quality audio but figured it could be salvaged with subtitles... Here is me in my usual class environment, asking leading questions until the professor stops calling on me. Enjoy staring up my nostrils as I try to keep my phone hidden from my eagle-eyed professor.
The purpose of the questioning was to try and start a conversation that we, in our country, are often not allowed to have. Today, we're conditioned to believe that anybody can do anything, "as long as you work hard!" And rhetoric other than that is too brutal. The taboo nature of the topic was proven to me when all of the students were suddenly awake for this lecture and asking questions for the first time... and it can be further proven by anyone angered by this video. It's not socially acceptable to question human nature anymore.
