We’re excited to announce Alias v013 after great feedback from our customers. The major change has been decomposing the previous Junk flag to Gibberish, Off-topic, and Low-effort. Now with this advanced junk detector, researchers can be extremely precise when automating their data cleaning process.

We ran v013 on our MTurk study below. Each panel shows the results of one 100-person survey.


We see a slight rise in human participants as minimum HIT rate increases, as well as a near complete elimination of ‘junk’ responses at the highest tier.

Sample answers from each flag are below. Question: What comes to your head when you think about Boston? Please give specific examples.

  • Human: The fact that it is located in the Northeast of the country. Boston has a baseball team called the RedSox as well. I also know that Boston is close to New York and other northeast states.

  • Low-effort: Good

  • Off-topic: Psychology is the scientific study of the mind and behavior. Psychologists are actively involved in studying and understanding mental processes, brain functions, and behavior and feel good in the view

  • Gibberish: Let’s take some examples to understand this better. You can target … Then, it comes into your head as your own thoughts but they are not your

  • GPT: When I think of Boston, several things come to mind:

    • Historical Significance: Boston is rich in American history, particularly associated with the American Revolution. Examples include the Freedom Trail, Boston Tea Party Ships & Museum, and landmarks like the Paul Revere House and Bunker Hill Monument.

    • Education and Universities: Boston is renowned for its numerous prestigious universities and colleges, such as Harvard University, Massachusetts Institute of Technology (MIT), Boston University, and Northeastern University…

We found Junk was too big of a catch-all, precisely because researchers have different exclusion criteria when it comes to tags like Low-effort. In addition to better junk flags, v013 provides better GPT detection, more sensitive behavioral analyses, and faster speed.
