A maize meme shows why you shouldn't trust social media

I find the immense potential of social media to spread scientific knowledge around the globe fascinating. Its ability to allow people to share anecdotal observations which can lead directly to some of the greatest discoveries is amazing. I was intrigued when a meme that claimed to show the results from a student study on genetically modified corn kept appearing on my social media feeds last week.

This photo, shared thousands upon thousands of times, shows two ears made of maize standing side-by-side. The label is for the one to the left.
