Selective perception and subjective perception

I thought the following quote, from an article in Time, explains with few words how "never the twain shall meet". (Rudyard Kipling)

Aren't we all guilty of this thinking or can we truly be objective?

>"Ray Aldag, a management professor at the University of Wisconsin's School of Business, points to two cognitive tricks: selective perception and subjective perception. Selective perception is our bias toward ignoring information that is at odds with our worldview. Subjective perception explains our tendency to couple uncomfortable information with reaffirming facts in order to make ourselves feel better."<
