What this topic is asking
The College Board (Topic 5.1) wants you to analyze the effects of computing innovations on people and society. The central idea is that a single innovation can have both beneficial and harmful effects, and that effects may be intended or unintended. You must be able to identify an innovation, describe a benefit and a harm, and judge whether each effect was a designed goal or an unforeseen consequence. This kind of impact analysis appears throughout the exam.
What a computing innovation is
Beneficial and harmful effects together
For example, ride-sharing apps benefit riders (convenience) and some drivers (flexible income), but can also harm taxi drivers' livelihoods and increase traffic. The same innovation does both.
Intended versus unintended effects
Effects fall into two categories:
- Intended effects are the outcomes the creators designed for: a navigation app intended to help people find routes.
- Unintended effects are consequences nobody planned. They can be harmful (routing traffic through quiet streets, eroding people's own navigation skills) or even beneficial (an app finding a popular use its makers never imagined).
The exam often asks you to label an effect as intended or unintended, so practice distinguishing them.
Try this
Q1. Give one example of a beneficial and one harmful effect of online social media. [2 points]
- Cue. Beneficial: it helps people stay connected and share information widely. Harmful: it can spread misinformation or enable harassment (any reasonable pair).
Q2. What is the difference between an intended and an unintended effect of a computing innovation? [2 points]
- Cue. An intended effect is an outcome the creators designed for; an unintended effect is a consequence nobody planned, which may be harmful or beneficial.

AP 2022 (style)1 marksMultiple choice. A social media platform is designed to help people stay connected with friends. Which statement best reflects how the CED describes the effects of such an innovation?
(A) A computing innovation has only the effects its creators intended.
(B) A single innovation can have both beneficial and harmful effects, including unintended ones.
(C) Harmful effects always outweigh beneficial ones.
(D) Effects on society cannot be analyzed.

The answer is (B).
The CED stresses that a single computing innovation can produce both beneficial and harmful effects, and that effects may be unintended even when the goal is positive (for example a platform meant to connect people can also enable harassment or misinformation). (A) ignores unintended effects. (C) overgeneralises. (D) is wrong: analyzing impact is a core skill.
Markers reward recognizing that one innovation can have both beneficial and harmful, intended and unintended, effects.
AP 2021 (style)4 marksCreate performance task (style). Identify a computing innovation and describe one beneficial effect and one harmful effect it has on society, noting whether each effect was likely intended or unintended.

A 4-point question on analyzing an innovation's dual effects (the explore-style impact prompt).
Model response: "GPS navigation apps are a computing innovation. A beneficial, intended effect is that they help people reach destinations efficiently and avoid traffic, saving time and fuel. A harmful, often unintended effect is that overreliance can reduce people's own navigation skills and can route heavy traffic through quiet residential streets, disrupting those communities."
This earns credit because it (1) names a specific innovation, (2) gives a clear beneficial effect labelled intended, (3) gives a clear harmful effect, and (4) labels each as intended or unintended. A response that lists only benefits, or stays vague, would not score fully.
