Bite-size: Social psychology and behavioral psychology both study human behavior, but they take different approaches to explain (or predict) behavioral patterns. The difference in analysis lies in what (or rather where) the main influence is coming from. Both fields recognize the interplay between internal states and external actions, but they differ mainly in their level of analysis.

Social psychology and behavioral psychology focus on different aspects and employ distinct approaches when studying human behavior. Social psychology examines how internal attitudes, beliefs, and emotions drive behavior. It focuses on the cognitive and affective processes that precede—and sometimes fail to align with—our actions. In contrast, behavioral psychology starts with observable behavior and explains it through external influences such as conditioning, reinforcement, and environmental cues, treating actions as primary and often viewing attitudes as secondary or emerging from those behaviors.

Focusing on consumer attitudes is crucial for advertisers because deeply held beliefs and values not only drive immediate purchasing decisions but also foster long-term brand loyalty. For instance, Nike’s “Just Do It” campaign taps into underlying attitudes of empowerment and resilience, encouraging consumers to adopt an identity centered around overcoming challenges rather than merely reacting to a discount or promotion. Similarly, Apple’s advertising emphasizes innovation and creativity, aligning with consumers’ desire to be seen as forward-thinking and unique. These campaigns do more than trigger a momentary response—they shape the way consumers view themselves and the brands they support.

In contrast to a behavior-first approach—which might rely on short-term incentives or promotions (for example, a 20% discount for Nike Club members) to condition immediate responses—the attitude-first strategy focuses on engaging deeper, intrinsic motivations. While a behavior-first approach may successfully prompt a purchase through temporary discounts, it rarely builds an emotional connection or long-term loyalty. By crafting messages that resonate with core attitudes and values, advertisers not only influence behavior but also create enduring relationships that persist beyond the initial transaction, leading to a more sustainable competitive advantage in the marketplace.

Bite-size: We often overestimate the character or personality of a person when making a judgment or evaluation, and instead ignore the very powerful influence of the context or situation we’re in.

This is called the Fundamental Attribution Error and it is the main argument for the importance of social psychology.

You're at a coffee shop, and the barista gets your order wrong. You might think, "They're careless and not paying attention to their job". However, they might be dealing with a rush of orders, feeling stressed, or new to the job. You initially attributed the error to a personal trait but in reality, there are situational factors that are more likely to have caused the mistake.

This example reminds us how easily we can overlook external pressures in everyday interactions. But it’s also something that plagues client-agency teams.

Perhaps misattributing lower-than-expected sales from a campaign due to audience preference, when situational factors might be at play. Message misalignment or customer journey gaps are two obvious ones, but it could also be (something that gets in the way of purchase), or less obvious factors like

You launch a high-budget campaign for a luxury watch brand—it features stunning visuals, celebrity endorsements, and a focus on exclusivity—but the brand sees little uplift in sales. People within the agency might conclude, "Consumers just don’t care about luxury watches anymore" (attributing the poor performance to a lack of interest or changing tastes). But what’s likely to be the case can be attributed to situational factors. Examples: message misalignment, customer journey gaps, over-saturated message or fatigue, or it was just a timing issue.
