According to neuroscientist Camilla Arndal Andersen, how consumers describe the taste of food can be misleading largely due to inherent biases. Among the most problematic is the “courtesy bias,” which comes into play when people respond with what they see as a socially acceptable opinion that doesn’t accurately reflect how they feel. There’s also the “bias blind spot,” in which we think we’re less biased than others. In short, we’re biased about our biases.
