Why Your Brain Hates Being Wrong: Belief Perseverance, Confirmation Bias & Cognitive Dissonance
In this episode of AP Psychology in 15, Mr. Bruns explores three important concepts from Person Perception and Attitude Formation & Change:
Belief Perseverance — Why do we continue believing something even after the evidence supporting it has been disproven?
Confirmation Bias — Why do we tend to notice, search for, and remember information that supports what we already believe?
Cognitive Dissonance — Why does it feel so uncomfortable when our behavior doesn't match our beliefs—and what do we do to reduce that discomfort?
We'll also examine classic psychology research that AP Psychology students should know, including:
• Wason's 2–4–6 task and confirmation bias
• Ross, Lepper & Hubbard's research on belief perseverance
• Festinger & Carlsmith's $1 vs. $20 experiment and cognitive dissonance
• The insufficient justification effect and how behavior can influence attitudes
Plus, Mr. Bruns breaks down the AP exam clues that help you quickly distinguish these concepts in multiple-choice questions and FRQs.

Person Perception: Why We Like, Compare & Judge Others
In this episode of AP Psychology in 15, Mr. Bruns breaks down person perception and four important AP Psychology concepts:

Who’s Really in Control? Understanding Locus of Control
In this episode of AP Psychology in 15, Mr. Bruns breaks down locus of control—the psychological concept that explores whether people believe their actions and choices influence outcomes or whether outside forces like luck, fate, circumstances, and other people have greater control.
You’ll learn the difference between:
Internal Locus of Control — “My choices and actions can make a difference.”
External Locus of Control — “Outside forces strongly influence what happens.”
Mr. Bruns uses relatable examples involving school, grades, sports, jobs, motivation, and everyday decisions to show how beliefs about control can influence thinking, expectations, motivation, and behavior.
Most importantly, you'll learn why internal doesn't automatically mean “good” and external doesn't automatically mean “bad.” Sometimes life really does involve circumstances beyond our control.

Person Perception & Attribution Theory (Social Psychology)
In this episode of AP Psychology in 15, Mr. Bruns explores Person Perception and Attribution Theory—the psychological processes we use to interpret people's behavior and explain why they do what they do.
You'll learn how to distinguish between dispositional attributions (the person) and situational attributions (the circumstances), including how intelligence and personality can influence behavior while situations can also affect performance.
Mr. Bruns also breaks down explanatory style, including the differences between optimistic and pessimistic explanations, and then tackles three important attribution biases that frequently appear in AP Psychology questions:
🎯 Fundamental Attribution Error — Why we tend to blame other people's behavior on their personality while overlooking the situation.
🎭 Actor-Observer Bias — Why we explain our own behavior through the situation but often explain someone else's behavior through their disposition.
🏆 Self-Serving Bias — Why we take credit for our successes but are more likely to blame outside circumstances for our failures.
Throughout the episode, real-world examples and AP-style scenarios help students recognize these concepts and apply them—not just memorize definitions.

Can We Trust the Results? Generalizability, Meta-Analysis, Statistical Significance & Effect Size
Can psychologists really take the results of one study and apply them to everyone? What does a p-value actually tell us? And does “statistically significant” mean that something is a BIG deal?
In this episode of AP Psychology in 15, hosted by Mr. Bruns, we break down four essential research-methods concepts you need to understand for the AP Psychology exam:
🧠 Generalizability — Can research findings from a sample be applied to a larger population?
📊 Meta-Analysis — What happens when psychologists combine the results of multiple studies to get the bigger picture?
🎯 Statistical Significance — What does p < .05 really mean, and why doesn't it prove that a hypothesis is true?
📈 Effect Size — How large or meaningful is the effect, even when a result is statistically significant?

Stats Without the Stress: Describing Data & Making Inferences
Statistics doesn't have to be scary! In this episode of AP Psychology in 15, Mr. Bruns breaks down the essential statistics concepts you need for AP Psychology—without turning the episode into a math lecture.
Learn how psychologists use descriptive statistics to make sense of data, including:
📊 Mean, median, and mode
📈 Percentile rank

🔔 Normal distributions
↔️ Positive and negative skew
Then we take the next step and explore inferential statistics—how psychologists use data from a sample to make conclusions about a larger population and determine whether results may reflect something beyond random chance.
Most importantly, you'll learn the AP Psychology test-day tricks that can save you from common mistakes, including the difference between percentage and percentile rank, why extreme scores affect the mean, and why the tail tells you the direction of skew.
By the end of this episode, you'll be able to look at a set of psychological data and explain what it means—exactly the skill psychologists use when turning numbers into evidence.

Research Detectives — Samples, Correlation & Causation
How do psychologists choose the people they study? What exactly does a correlation tell us? And why is correlation NOT the same thing as causation?
In this episode of AP Psychology in 15, Mr. Bruns puts students in the role of research detectives as we explore the foundations of psychological research.
In this episode, Mr. Bruns investigates:
Population vs. Sample
Random Selection
Correlational Research
Correlation Coefficients (-1.00 to +1.00)
Positive vs. Negative Correlations
Variables
Scatterplots
Why correlation does NOT indicate causation
Illusory Correlation
Regression Toward the Mean
Using real-world examples—from sleep and test scores to ice cream and shark attacks—Mr. Bruns breaks down these concepts in a way that makes them easier to recognize on the AP Psychology exam.

Mr. Bruns begins by examining how theories advance psychological science and explain the essential vocabulary every AP Psychology student should know, including peer review, theories, hypotheses, null hypotheses, falsifiability, operational definitions, and replication.
Next, Mr. Bruns compares the major non-experimental research methods—case studies, naturalistic observation, and surveys—learning when psychologists use each method and the strengths and limitations of each.
Finally, Mr. Bruns tackles several of the most common research biases tested on the AP exam, including social-desirability bias, self-report bias, sampling bias, and wording effects, with real-world examples to help these concepts stick.
