the meaning of 'in its light'
The passage below comes from Mastermind: How to Think Like Sherlock Holmes By Maria Konnikova.
http://sourcesofinsight.com/mastermind-how-to-think-like-sherlock-holmes/ What’s more, not everything is as black and white—or as pink and white, as the case may be—as the elephant. And not everything that our intuition says is black and white is so in reality. It’s awfully easy to get tripped up. In fact, not only do we believe everything we hear, at least initially, but even when we have been told explicitly that a statement is false before we hear it, we are likely to treat it as true. For instance, in something known as the correspondence bias (a concept we’ll revisit in greater detail), we assume that what a person says is what that person actually believes—and we hold on to that assumption even if we’ve been told explicitly that it isn’t so; we’re even likely to judge the speaker in its light.I'd like to ask two questions regarding the underlined 'in its light'.
First, what does 'it' refer to?
Second and last, what does 'in its light' mean?
Regards.
