Speeder Detection

Automatically flag respondents who complete a survey in an implausibly short time to preserve data quality.

A speeder is a respondent who finishes the survey in an implausibly short time, typically without actually reading the questions. Speeders often appear among incentive-driven panels, or as a side effect of automated answer generation. Catching them is the most fundamental step in fraud detection.

How detection works

kicue uses a simple, robust threshold:

  • Threshold = number of questions × 3 seconds
  • If total completion time is below this threshold, the response is flagged as a speeder

For example, a 30-question survey triggers the flag below 90 seconds, and a 50-question survey below 150 seconds.

When it helps

  • Panel-based surveys where incentive hunters may submit careless answers
  • Open-web surveys that attract drive-by respondents with little interest in the topic
  • Surveys with many matrix questions that require careful reading

Flag states

Each detected response is assigned a status:

  • pending — the default state immediately after detection
  • confirmed — a reviewer has marked the response as fraudulent
  • dismissed — a reviewer has marked the response as acceptable

Reviewing on the monitoring screen

The Flags tab on the monitoring screen lets you review detected speeders, including:

  • Per-respondent completion time
  • Detection timestamp
  • Direct link to the raw response

Excluding from tabulation

Responses marked as confirmed can be excluded from tabulation by turning on the Exclude fraud toggle. See Flag Management & Exclusion for details.
