VERA FILES FACT CHECK: Gadon gets two things wrong in rant vs. SWS, Pulse Asia

Read this fact check in Filipino

Lawyer Lorenzo “Larry” Gadon, who is seeking a Senate seat, made two false claims in an expletive-laden outburst against polling firms Social Weather Stations (SWS) and Pulse Asia Research.

Trailing in the latest voter preference surveys, Gadon on Jan. 21 petitioned the Commission on Elections (Comelec) to bar the two polling firms from releasing “flawed and fake” pre-election results, saying surveys are a “mind conditioning scheme.”

STATEMENT

Weeks after media published senatorial surveys attributed to SWS and Pulse Asia, he slammed the two polling firms in a viral Facebook video:

“Fifty-five milyon ang botanteng Pilipino. Mag-su-survey sila ng 1,800 tapos idedeklara nila ‘yung mga top 12 daw? Aba eh nakapakalaking kalokohan! (There are 55 million Filipino voters. They survey 1,800 people and declare a top 12? That’s a big joke!)”

The video, shared by 61 Facebook pages including that of former Communications Assistant Secretary Mocha Uson, could have reached 7.3 million people.

FACT

There are more than 61 million registered voters who will decide the outcome of the May 13 elections, according to the Comelec. Gadon understated the figure by 6 million.

In September 2018, SWS polled 1,500 adults nationwide: 600 from Balance Luzon and 300 each in Metro Manila, Visayas and Mindanao.

In December, Pulse Asia interviewed 1,800 adults, who were chosen based on this detailed distribution.

The number of respondents in the SWS and Pulse Asia electoral surveys have statistical basis.

The number of people polled in each survey were derived through “sampling,” a statistical process that researchers worldwide use to select a sample of individuals that would represent an entire population.

The Philippine Statistics Authority, the government’s central statistics agency, uses sampling in its nationwide surveys of households to gather data on the country’s labor force, health demographics, income and expenditure, among others.

Researchers also use sampling to find out which traits society values in men and women, to investigate the link between social media use and depression, and to rank the world’s happiest countries, among other things.

In election surveys, instead of polling every member of the population—for instance, 61 million registered Filipino voters—polling firms determine a representative “sample” to mirror the views of the voting population in a given period.

The American Association for Public Opinion Research (AAPOR), a group of public opinion and survey research professionals, explains the logic behind sampling: “If we can choose respondents randomly and appropriately from the larger population, the results from that random sample will be very close to what we would get by interviewing every member of the population.”

The World Association for Public Opinion Research (WAPOR) and the World Association for Social, Opinion and Market Research (ESOMAR) say that while pre-election polls are expected to be accurate in their estimates of a voting tally, they “should not be seen as predictions per se,” but as “a reflection of opinion at the time the poll was conducted.”
