San Antonio residents looking to make sense of the flood of poll numbers can turn to a trusted local source. Bryan Gervais, director of the University of Texas at San Antonio Center for Public Opinion Research, outlined a simple checklist for voters to evaluate the credibility of any political poll.

Ask the right questions

According to Gervais, the first step is to identify who commissioned the poll and who funded it. “Knowing who paid for the survey helps you spot potential bias,” he said. He also recommends checking the sample size: a larger, well‑balanced sample is more likely to reflect the broader electorate.

Next, voters should verify when the poll was conducted and what exact questions were asked. Timing matters because public opinion can shift quickly, especially in a heated election season. Gervais cautions that a poll taken weeks before an election may not capture late‑breaking developments.

Look for methodological transparency

Gervais points readers to the American Association of Public Opinion Research (AAPOR) Transparency Initiative. Organizations that belong to this initiative publicly disclose their sampling methods, weighting procedures, and margin of error. “Those who are transparent about how they collect data are generally more trustworthy,” he explained.

He added that reputable pollsters often reuse questions that have been tested and validated over time. This practice reduces the risk of wording that could unintentionally sway respondents.

Understand the margin of error

Even a well‑designed poll comes with a margin of error, typically expressed as plus or minus a few points. Gervais illustrated this with a hypothetical: if Candidate A shows 49 % support and Candidate B shows 47 % with a ±3‑point margin, the race is essentially a statistical tie. Voters should avoid over‑interpreting small leads that fall within the margin.

Beware of online “polls”

Gervais warned that internet polls allowing anyone to click and vote rarely represent the electorate. Such surveys lack the controlled sampling needed to mirror the voting population and should be treated with skepticism.

By asking these straightforward questions—who funded it, how many people were surveyed, when it was conducted, what was asked, and whether the methodology is transparent—voters can separate reliable data from speculation.

Why it matters for Texas voters

With the 2026 midterm elections approaching, accurate polling helps citizens gauge the political landscape and make informed decisions at the ballot box. Gervais emphasized that an informed electorate is a cornerstone of a healthy democracy, aligning with the values of personal responsibility and civic engagement.
