Prejudice is a strong barrier to effective listening, as it follows preconception that are baseless about your spouse or a subject matter of discussion between the two of you. (Please see yesterday’s devotional).
Cognitive bias is a form of prejudice that has to do with the way our brains perceive new ideas, this can make you view your spouse in a particular negative way without a clear basis. Two cannot work together except they agree neither can you and your spouse form a forcible team that can bring down ten thousand with cognitive-bias. Example of cognitive is: marriage is a scam, fair ladies are promiscuous, marriage is a necessary evil, my spouse does not love me and more. The only easy way out of cognitive-bias is to deliberately choose to renew your mind with the word of God. Marriage is a necessary evil.
