Credit scores, which represent how likely a person is to pay his or her bills, affects almost every aspect of an American's financial life. One key benefit built into the credit scoring system is its nondiscriminatory practice of using just numbers to determine a person's creditworthiness. "Credit scoring when it was first developed was an advancement," said Chi Chi Wu, staff attorney at the National Consumer Law Center. "It is better than having some banker sit across from you and judge you and read the information in your credit report, because they bring a lot of their subjective analysis and their own life experience into the analysis. And if their life is different than your life, that analysis can be flawed." But despite the good intentions of credit report companies, many experts argue that the current system is still discriminatory. A survey of 5,000 U.S. adults found that more than half of Black Americans reported having a low or no credit score, compared to 41% for Hispanics, 37% for whites and 18% for Asian Americans. Having a low or no credit score can often bring severe financial consequences. Forty-two percent of Americans said their credit scores prevented them from accessing financial products like credit cards or loans. Sally Taylor, vice president and general manager at FICO, added, "It's important to note that credit scores didn't create some of the social economic disparities. They simply reflect the social economic disparities that are out there. The conversation should focus on addressing the root cause of these differences."
