Barbara Carvalho

Overview

Barbara Carvalho is identified in the supplied Planet Money episode as director of the Marist Poll, responsible for survey questions, methodology, and statistical analysis.

Current Profile

Carvalho presents polling as an adaptive measurement practice: historical errors motivate random selection, contemporary nonresponse motivates weighting and new contact modes, and disappointing experimental results remain useful when they clarify what a question does and does not measure.

Key Characteristics

• Uses historical polling failures to distinguish sample size from sample representativeness.
• Oversees question design, survey methodology, and statistical work at Marist.
• Treats weighting as a response to identified sample imbalance rather than a universal cure for nonresponse.
• Frames failed forecasting experiments as evidence that can redirect research toward turnout and voter expectations.

Evidence

Methodological leadership

• We try to fix election polling (update) attributes Marist’s questions, methodology, statistical work, historical explanation, and weighting discussion to Carvalho.

Experimental interpretation

• We try to fix election polling (update) reports her acceptance of the poor 2022 crowd-wisdom forecast as part of testing and learning rather than evidence to conceal.

Qualifications

• This profile relies on one edited podcast account rather than Carvalho’s publications or a complete institutional biography.
• The episode does not isolate which parts of Marist’s 2022 design caused its accurate national estimate.
• Claims about current turnout predictors and continuing 2026 research are time-specific and source-reported.

What Changed

• Established Carvalho’s role in the wiki as the methodological voice for the Marist polling case.
• Added her experiment-oriented interpretation of an unsuccessful forecasting adjustment.

Relationships

• Marist Poll - organization she directs in the supplied source.
• Election Polling Representativeness - central methodological problem in her historical and current account.
• Crowd-Wisdom Polling - experiment she evaluates and continues to study.
• Planet Money - program through which her account is presented.
