Adverse impact is a hiring practice or screening step that disproportionately excludes a protected group in Intro to Business. It shows up when selection results are uneven, even if the rule looks neutral on paper.
Adverse impact in Intro to Business means a hiring step screens out members of a protected group at a higher rate than other applicants. The practice may be neutral on the surface, but the results show a pattern of unequal outcomes in employee selection.
You usually see this concept when a business is comparing how different groups move through the hiring funnel. A company might use an application form, aptitude test, background check, or interview, then look at who gets filtered out at each stage. If one group consistently clears the step at a much lower rate, that step may create adverse impact.
This is where the math side of the term matters. A common check is the 80% rule, also called the four-fifths rule. If the selection rate for one group is less than 80% of the rate for the highest-selected group, that can signal a problem worth investigating. It is not the only way to think about fairness, but it gives managers a quick screening tool.
Adverse impact is not the same as intentional discrimination. A company can use a policy without trying to treat anyone unfairly and still end up with unequal results. That is why businesses have to look at both the process and the outcome, not just the wording of the policy.
If adverse impact shows up, the business has to ask whether the practice is job-related and tied to business necessity. Managers also look for alternatives that would measure the same skill with less exclusion. In Intro to Business, this usually comes up in the employee selection unit as part of legal compliance, ethics, and smart hiring decisions.
Adverse impact matters because it connects hiring decisions to fairness, risk, and business performance. In Intro to Business, you are not just memorizing a legal term. You are learning how a company can lose strong candidates, damage its reputation, or create legal trouble if its selection process filters people unevenly.
It also helps you read hiring decisions more carefully. A test, interview question, or background screen might look neutral, but the results can still favor one group over another. That is a big idea in employee selection, because managers have to judge both the method and the outcome.
This term also fits into ethics. Businesses are expected to build diverse, equitable workplaces, and adverse impact is one sign that a process may be working against that goal. When you see it in class, think about whether the company chose the best screening tool for the job or just the easiest one to use.
For assignments, this term often shows up in case studies where you identify which stage of hiring created the problem and suggest a better option. It is one of the clearest places where business law, human resources, and decision-making overlap.

Disparate impact is the broader legal idea behind adverse impact. In business class, you may see the terms used almost interchangeably, but adverse impact often describes the hiring result itself, while disparate impact is the legal frame for unequal outcomes from a neutral policy.
Protected Group
Adverse impact only makes sense when you can identify who is being affected. A protected group is the category of people the law shields from discrimination, such as race, color, religion, sex, or national origin. When one protected group is screened out at a higher rate, that is the pattern you examine.
Applicant Screening
Applicant screening is the larger process where adverse impact can appear. Each step, like a form, test, or interview, removes some candidates from the pool. If one screen eliminates a protected group more harshly than others, the whole selection process can become unfair.
Aptitude Tests
Aptitude tests are a common place to check for adverse impact because they seem objective but can still produce uneven group results. In Intro to Business, you may be asked whether the test measures a real job skill or whether it excludes qualified applicants without a business reason.
A quiz question or case study usually asks you to spot which hiring step created the uneven result. You might compare selection rates, apply the 80% rule, or decide whether a screening tool is job-related. If the case mentions interviews, tests, or background checks, look for the stage where one group drops out at a much higher rate. Then explain whether the company can defend the practice with business necessity or should use a less exclusionary option.
These terms are closely related, so they get mixed up a lot. Adverse impact is the observable hiring outcome, a practice that excludes one protected group more than others. Disparate impact is the legal concept that focuses on whether a neutral policy creates that unequal result. In class, adverse impact is often the business-process version of the same problem.
Adverse impact is uneven hiring results that hurt a protected group more than other applicants.
The term shows up in employee selection, especially in screening, testing, interviewing, and final hiring decisions.
The 80% rule is a quick way to check whether one group is being selected at a much lower rate than the strongest-performing group.
A business can still have adverse impact even if it did not mean to discriminate.
If a policy creates adverse impact, the company should ask whether it is job-related and whether there is a fairer alternative.
Adverse impact is when a hiring practice or selection step excludes a protected group at a higher rate than others. In Intro to Business, it shows up in employee selection as a fairness and legal issue. The policy may look neutral, but the results reveal unequal treatment.
A common check is the 80% rule, where you compare selection rates across groups. If one group is selected at less than 80% of the rate of the highest-selected group, that can signal adverse impact. It is a warning sign, not the final word, so businesses still look at the job connection and the full context.
Not exactly. Discrimination usually implies unfair treatment, often intentional, while adverse impact is about the results of a neutral-looking practice. A company can create adverse impact without meaning to, which is why managers have to review outcomes as well as intentions.
It can appear in recruitment, application forms, aptitude tests, interviews, background checks, and final hiring decisions. In class examples, the problem is often traced to one screening step that removes one group much faster than others. That is why employee selection is a funnel, not just a single decision.
