This newspaper comprehensively reports from foreign media A new research discovery，If the questionnaire contains too many bet365 live casino games of the same type，Returned data may be unreliable。

According to the official website of the University of California, Riverside, reported on January 28，Ye Li, assistant professor of management at the school，Transliteration) and others in the new study "Asking More，Less for Gain: Additional bet365 live casino games Undermine External Validity》中，Inspected market research、Whether quantitative questionnaire surveys commonly used in economics or public policy research collect more data, the better，Will asking too many bet365 live casino games actually reduce the quality of the answers。

The researchers conducted four sets of experiments involving choice and preference issues，Experimental results display，As participants answered an increasing number of repetitive bet365 live casino games with a similar structure，Their answering decisions began to “adapt” to the questionnaire，Processing less information、Learn to give greater weight to certain attributes、Taking "mental shortcuts" to certain combined properties。In one set of experiments，The questionnaire asked participants about their preferences for laptops with different configurations，For example，Are you willing to sacrifice screen size to a certain extent to get more storage space。

Researchers found，When participants continue to answer slightly different bet365 live casino games、When you have bet365 live casino games about laptop configuration，Participants read the bet365 live casino games carefully when answering the first two or three bet365 live casino games，But soon participants will only answer on a certain parameter (such as battery life)。Although scientists know that humans adapt to their environment，But most behavioral research methods used to measure preferences underestimate this factor。“When faced with 6-8 problems with very small differences，People have begun to use mental shortcuts，When faced with more problems，People get tired，Tend to give the same answer。"Li Ye said。

This new study provides some information that can help enhance the validity of bet365 live casino games survey data，Way to save time and money at the same time。For example，Process tracing methods can be used to identify “adaptation”，Determine whether the validity of the data is threatened；You can continuously change the task form、Add padding question、Set rest periods to weaken or delay "adaptation"；Can diversify question formats and contexts，Integrate multiple measurement methods to maximize validity。
