Not too many years ago, the credit world was much different than it is today.
Credit bureaus operated in near secrecy, gathering information in ways you'd not believe.
Did you know that Retailer's credit (now Equifax) used to use information gathered about you from the Welcome Wagon representative? Quality of your home, furnishings, opinion of your character, etc?
Trying to see what was in you report was nearly impossible. It could be absolutely wrought with error and incorrect information- you'd never know. Even if you did know, you couldn't correct it.
Lending decisions were made partly on the content of that report, and partly- sometimes mostly- on the whim of the underwriter at the bank you were applying at. If you didn't "look right"- or were of a minority group, or lived in the wrong neighborhood. etc- forget it.
That started to change as credit cards became popular in the late 1960's. There was no way to personally interview an applicant who lived states away from the issuing bank, nor could the credit reports available at the time be relied upon. Many disasterous lending decisions were made using the information in those reports.
Meanwhile, congress had begun investigating discrimination in housing loans, and the practices of collection agents. (there's another story, lol)
The result was the FCRA, enacted in 1971 and later the FDCPA in 1977.
Here is a timeline of lending industry reforms, showing the emphasis in the '70s on cleaning up abusive/discriminatory practices:

The FCRA literally forced CRA"s to clean up their act. As the data in consumer reports became more standardized and more accurate (!) lenders began to rely more on them, less on the underwriters' gut feeling.
Lenders begain to develop their own automated risk-scoring, but the results were inconsistent and inaccurate. The often still factored in things like age, gender, etc.
Fair Isaac and company capitalized on that movement, and on the push to reform mortgage lending by compiling their risk model scoring.
Finally released in the 1980's, it was touted as an impartial, consistent way to evaluate credit applications, taking the prejudice and instinct out of the equation.
Given that lenders were under pressure from Congress to eliminate discriminatory lending practices, FICO seemed like an answer to their dilemma. They jumped on it and have never really looked back.
Many still do manual underwriting, and most employ an internal risk calculation of which FICO is only a portion.
But those '60 s and '70s lawsuits and congressional action went a long way to eliminate the prejudice that had saturated the financial industries.
FICO has been accused over the years of still factoring race, age, gender into their equations, the most common complaint is that of zip-code discrimination. I don't personally believe that any of that is used in score calculations and will leave that discussion to those who know more about it. But in a historical sense, FICO did wonders to level the playing field.
Not until very recent years could a consumer see their credit score- a remnant of that old secrecy pact.
California's SB1607 was the first law to mandate consumer disclosure of scores- in 2000!
Eloan was the first source for consumers to see their score, causing Fair Isaac to attempt to strong arm both them and Equifax back in to silence.
But the cat was out of the bag, Fair Isaac could not crawl back in to the dark days for long and eventually, under tremendous pressure, relented.
