Legacy sites that include short catchphrases about players in their rankings. Does that cause cognitive bais?  

Yes, short catchphrases or taglines in player rankings can (and often do) introduce or amplify cognitive biases. These snappy descriptors act as mental shortcuts that shape how readers perceive and evaluate players, often in ways that go beyond the underlying stats or performance.

Key Biases Involved

Several well-documented cognitive biases make catchphrases particularly influential:

• Halo Effect (and Horn Effect): A single positive trait or label creates an overall positive impression, spilling over to unrelated attributes. A catchphrase like "Clutch King" or "Game-Changer" can make a player seem more skilled, reliable, or valuable across the board, even if their stats are middling. The reverse ("Bust" or "Overrated") creates a negative halo. Studies on labels (e.g., descriptive food names or diagnostic labels) show this reliably boosts or lowers expectations and evaluations. papers.ssrn.com

• Anchoring Bias: The catchphrase serves as an initial "anchor" that pulls subsequent judgments toward it. Readers start with the phrase and interpret data through that lens, giving it more weight than drier rankings or metrics.

• Framing Effect: How information is presented matters. A vivid, memorable tagline frames the player positively or negatively, influencing decisions like fantasy drafts, debates, or even how scouts/coaches view them. Evocative names or labels consistently outperform neutral ones in appeal and perceived quality.

• Confirmation Bias and Salience: Once anchored, people notice and remember info that fits the catchphrase while downplaying contradictions. Salient, funny, or striking phrases stand out more (bizarreness/humor effects), making them stickier than neutral analysis. buster.medium.com

• Labeling and Self-Fulfilling Effects: In talent evaluation, persistent labels (even algorithmic ones) can shape opportunities, creating feedback loops where the labeled player gets more/less playing time, reinforcing the original tag. mdpi.com

• In sports scouting and evaluation, cognitive biases like confirmation and framing heavily influence decisions. Scouts focus on info confirming preconceptions, and context/framing alters perceptions.

• Descriptive or evocative labels reliably shift evaluations in consumer psychology, education, and gaming—similar mechanisms apply to sports media.  papers.ssrn.com

• Media and fan discussions amplify this; negativity bias, team identification, and overreactions in fantasy sports show how narratives distort objective assessment. rochester.edu

Legacy sites (e.g., older sports outlets) often use these for engagement—catchphrases are memorable and drive clicks/shares—but they trade some objectivity for readability. 

Modern data-driven sites try to minimize this with stats-heavy formats, though even they aren't immune.  

SCIOFF (Science of Fantasy Football) promotes less cognitive bias than legacy sites — and actively works to reduce it compared to most fantasy resources, including many dedicated ones.

Mitigating It

Awareness helps: Cross-reference rankings with raw data, multiple sources, or neutral metrics. Treat catchphrases as starting points or marketing flair, not core analysis. As a reader, pausing to ask "Would I rate this player the same without the tagline?" reduces the pull. 

In short, yes—they introduce bias by design, leveraging how our brains process information quickly and heuristically. It's not always malicious, but it systematically affects perceptions in sports discourse.
