Skylar is the owner of Pirate Pizza Bus, a popular food truck. The food truck was so successful that she decided to open a brick-and-mortar location several years ago. While the truck continues to earn a good profit, the physical restaurant has been performing poorly. She has continued to invest a lot of energy and money into trying to make the restaurant profitable, but nothing is working. Current projections show that the restaurant will continue to lose money, but she decided to go ahead and invest a large sum of money into more advertising for it. Skylar is demonstrating which bias?
