Public opinion polling has come under scrutiny following a new partnership between PennLive and Bravo Group, which has been described by some as more marketing than methodological advancement. In a recent column, Bravo Group CEO Chris Bravacos presented his company’s “Morning Scrapple” poll as a groundbreaking approach. However, this assertion overlooks the robust history of innovation and adaptation within the polling industry.
The polling sector has consistently engaged in self-reflection and improvement since public election polling began in the 1930s. According to research from the Pew Center, the landscape has evolved significantly. A report indicated that more than three out of five pollsters in the United States adjusted their data collection methods between 2016 and 2022. This suggests that the industry is not clinging to outdated practices, but rather adapting to new realities.
A key development in modern polling is the shift away from reliance on traditional telephone surveys. Reputable pollsters are increasingly allowing respondents to choose how they participate, whether through phone interviews or online questionnaires. This flexibility not only enhances participation rates but also enables researchers to assess the varying impacts of different data collection methods.
Despite these advancements, challenges remain, particularly concerning online surveys. Issues such as inattentive respondents and fraudulent participation can skew results. A troubling statistic from a marketing research industry group indicates that between thirty to forty percent of online survey panelists may be fake. This raises significant concerns for the non-probability panels, such as those being utilized by PennLive’s new partner, Bravo Group.
Non-probability panels rely on self-selected participants who often receive compensation for their involvement. In contrast, probability samples—which form the backbone of reliable polling—begin with a comprehensive list of the population. Participants are then selected randomly from this list, ensuring a more accurate representation of public sentiment. The difference in methodology is critical: probability samples are grounded in established random sampling theory, while non-probability samples often reflect the researchers’ assumptions about the population.
An analysis of polling methods in Pennsylvania for the upcoming 2024 elections illustrates the impact of these methodological choices. Research indicates that opt-in samples, which are promoted as innovative by some non-probability designers, tend to be approximately half as accurate as their probability-based counterparts. This discrepancy in accuracy can lead to misleading narratives about electoral outcomes.
As PennLive embarks on this new partnership, the implications extend beyond marketing strategies. The potential for miscommunication regarding polling strengths and limitations could exacerbate existing partisan mistrust. Furthermore, failing to acknowledge the limitations inherent in any polling method risks undermining the credibility of the entire discipline.
In summary, while exploring a variety of tools for assessing public opinion is valuable, it is essential to maintain transparency about the strengths and weaknesses of each method. The distinction between marketing and responsible journalism lies in the commitment to presenting clear, accurate information. Berwood Yost, director of the Franklin & Marshall College Poll, emphasizes that understanding these differences is crucial for the integrity of polling practices moving forward.
