I work in the credit card field in North America, and I am involved in FICO. Similar to the functions of other credit bureaus, the American Consumer Fair Lending Act requires an institution to calculate a credit score specifically for use in everything from credit cards to home mortgages. Loans. It not only ensures fairness, but also considers risks. The algorithm itself is fair. The specific consideration criteria have been introduced upstairs and will not be repeated here. Personally, the disadvantages are as follows: Lack of real-time performance. For example, if you want to buy a new house, you need to prepare early to improve your credit score so that you can get a lower interest rate. Of course, some people talk about reducing speculation. This can be discussed in another topic. The weight of each criterion remains fixed. Since everyone’s consumption habits and cycle length are different, it is difficult to ensure the most realistic response. There is a lack of prediction of future credit risk. The current score can only reflect the past and present, and cannot show the individual's credit potential. Obviously, this is different for everyone. We have already started working on this part to increase the number and stability of our acquisitions.
