While reviewing the textbook, it can be said that there are always two ways of identifying the biases. The two terms can be factual and selection bias. The factual bias basically helps us in understanding the factual and empirical claims which are false and to try to justify the particular given position in accordance with the information that is being used. On the other hand, selection bias tends to focus on the particular fact which helps in understanding the challenges that are proposed while supporting a particular situation.
