What is Bias?
1
Subjectivity
A strong inclination or prejudice for or against one person or group, especially in a way considered to be unfair.
2
Loaded Language
Using words with strong positive or negative connotations to influence the reader's feelings.
"The facts may be the same, but the frame is what changes the picture."
The Sound of the Text: Tone
Positive
Optimistic, admiring, celebratory, encouraging.
Negative
Skeptical, critical, cynical, hostile, mocking.
Neutral
Objective, factual, detached, matter-of-fact.
PRO TIP: To find tone, look at the adjectives and adverbs the author uses to describe people and events.
The Investigator's Code
How to annotate for bias while you read:
Highlight "Loaded" words (very positive/negative)
Circle facts that can be proven true
Square opinions or feelings
Practice Check
"The arrogant senator refused to listen to the desperate pleas of the fifty protesters."
Notice how "arrogant" and "desperate" push you to feel a certain way about the characters.

Investigator's Briefing
Your task is to analyze two press releases regarding the proposed Greenview Park Project . Use your highlighter and pen to annotate for loaded language (words with strong emotional weight) and author bias. Look for adjectives that tell you how the author wants you to feel.
Source A
A Vision of Growth for Greenview
"The visionary Greenview Park Project represents a glorious opportunity to revitalize our weary downtown. This magnificent oasis will replace a crumbling, eyesore of a parking lot with lush meadows and vibrant playgrounds. It is a bold, essential step forward for our community’s well-being. Forward-thinking citizens are already celebrating this gift to our children."

The Reckless Cost of Greenview
"The reckless Greenview Park proposal is a direct threat to our local economy. By destroying vital parking infrastructure, the city will suffocate downtown businesses and drain taxpayer wallets for a purely decorative project. This misguided waste of space ignores the actual needs of working families. Concerned residents must stop this expensive vanity project before it's too late."

"Bias Sleuth" Answer Key
Source A Analysis
Tone: Optimistic, Visionary, Encouraging, Persuasive.
Evidence: "Visionary", "Glorious", "Magnificent", "Gift".
Bias: Extremely pro-park. Frames the project as an essential "gift" and labels opposition as "weary" or "eyesores."
Source B Analysis
Tone: Critical, Alarmist, Skeptical, Hostile.
Evidence: "Reckless", "Threat", "Suffocate", "Waste of space", "Vanity project".
Bias: Strongly anti-park. Frames the project as a "threat" and an economic "recklessness."
Discussion Synthesis Question (Suggested Answer)
"Both authors use the same basic facts (a parking lot is becoming a park for $2.50 cost/tax impact), but they use connotative language to frame those facts. Source A focuses on aesthetic/community gain, while Source B focuses on economic loss/inconvenience. This demonstrates that 'truth' in informational text is often filtered through the author's purpose."
Pro-Tip: "Fact vs. Frame"
Challenge students to rewrite one of the press releases to be 100% neutral. They will quickly find that removing all adjectives makes the text much shorter and drier, highlighting how much "flavor" authors add to influence readers.
Common Misconception
Students often think "bias" means "lying." Clarify that an author can be biased while only using true facts. Bias is about emphasis and selection of which facts to tell and how to describe them.

Boston Massacre Texts Primary Source Dossier
Subject: The Incident on King Street (March 5, 1770)
Confidential Case File
#1770-BM
Historical Context
Tensions in Boston were high in early 1770. British soldiers were stationed in the city to enforce tax laws, which the colonists hated. On the snowy night of March 5th, a crowd gathered around a lone British sentry. When more soldiers arrived to help him, a confrontation turned deadly. Below are two sworn statements given after the event.
SOURCE 1
Captain Thomas Preston, British Army
"The mob increased and were more outrageous... they struck our guns with clubs and threw snowballs. They yelled, 'Fire if you dare!' and 'Come on, you rascals!' I was between the soldiers and the mob, parleying with them to keep them at peace. A soldier was struck by a stick and immediately fired. On which, another soldier fired. I asked the soldier why he fired without orders. They said they heard the word FIRE and thought it came from me. I was not in a position to give such an order."
SOURCE 2
Samuel Drowne, Boston Resident
"I saw a party of about ten soldiers come out with their bayonets fixed. The crowd was small and mostly boys, who were laughing and talking. I saw the officer standing behind his men. He was waving his sword and looking very angry. I heard him distinctly cry out, 'FIRE!' and then the soldiers fired their guns into the people. They fired again and again. The people were unarmed and had no chance to defend themselves against such cruelty."
