Journalism: The first “message” received is the one remembered, even if later proven as false.
Reports of a polar bear spray painted with “T-34” on its side were greatly exaggerated. The tagging was done by scientists, not pranksters. The bear had been rummaging a garbage dump and scientists wanted to see if it was returning. They tagged it with a short duration ink; this was not graffiti by pranksters as initially reported. Typical of this type of report, the original source for the video was unknown, the back story was unknown, and the video was shared on social media by an environmental activist. Media then used social media as a primary source. What could possibly go wrong?
