The Cognitive Biases We Measure

Neuroscience Summary

Cognitive biases are systematic distortions in political judgment that undermine electoral rationality (Kahneman's System 1). Civicamente measures citizen immunity to three primary democratic biases: Confirmation, Coverage, and Simplification.

Cognitive biases are mental shortcuts that distort how we interpret information. Identified by Daniel Kahneman and Amos Tversky (Nobel Prize 2002), we now know they systematically influence political decisions. Civicamente measures three fundamental ones.

Statistical evaluation error

Air safety vs driving

Confirmation Bias

Tendency to seek, interpret, and remember only information that confirms existing beliefs, ignoring contrary evidence.

A voter who consults only sources aligned with their political orientation is 73% more likely to incorrectly evaluate an objectively neutral legislative proposal (Pew Research Center, 2021).

Emotional Impact (Coverage)

Instinctive reaction to sensationalist news, where decisions are driven by emotions rather than structural facts. Kahneman's 'System 1' — fast, intuitive thinking — dominates political judgment in 95% of daily decisions.

After a single plane crash, public support for air traffic restrictions increases by 40%, despite flying remaining statistically 287 times safer than driving (Slovic et al., 2004).

Simplification Bias

Preference for easy explanations and binary (Yes/No) answers to inherently complex problems. In Switzerland, popular initiatives with simplified wording receive on average 12% more votes than those with detailed text, regardless of merit (University of Zurich, 2019).

In the 2020 Swiss federal vote on the Responsible Business Initiative, post-vote analysis showed that 34% of voters had not understood the difference between the initiative and the counter-proposal, basing their choice on simplified slogans.

Sources and interpretation limits

Civicamente offers an educational self-assessment. Theoretical references do not constitute independent validation of its score. The Civic ID is not an official document and does not affect voting rights. Results from voluntary participants do not represent the whole population.

Vosoughi, Roy and Aral (2018) studied news diffusion on Twitter from 2006 to 2017. It does not validate the Civicamente test or establish a universal effect on voting behaviour. MIT — Vosoughi, Roy & Aral (2018)
