When the word'data' is talked about in artificial intelligence'bias' is often mentioned alongside the given discussion. I will have a general discussion of bias first that will be related to subjectivity and objectivity. Whereafter I will return to a summary of things to consider in relation to the development of artificial intelligence. "Bias is disproportionate weight in favour of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. Biases can be innate or learned. People may develop biases for or against an individual, a group, or a belief. In science and engineering, a bias is a systematic error. Statistical bias results from an unfair sampling of a population, or from an estimation process that does not give accurate results on average."
