What is the Behavioral Analytics Score?

The Behavioral Analytics Score (BAS) measures the quality of typing behavior to distinguish between natural human input and potentially artificial or automated responses. It helps detect answers generated by AI bots, scripts, or copy-paste actions—enhancing the reliability and authenticity of survey data.

​
How does the Behavioral Analytics Score work?

BAS analyzes each keystroke, the structure of the entered text, and the timing of inputs. It evaluates:

  • Typing speed and rhythm
  • Standard deviation of keystroke intervals
  • Timing consistency relative to text structure
  • Copy-paste actions (i.e., no keystroke activity)

These signals are combined to detect patterns that deviate from natural human typing.

Typing Patterns

Natural Human Typing
Character-by-character input with natural pauses, consistent rhythm, and normal variations—typical of genuine human behavior.

Low-Effort Human Typing
Still human, but with less consistent or more erratic timing—often seen in low-effort responses.

Auto-Complete Enhanced Typing
Combines typing with auto-complete suggestions. Detected by bursts of text insertion that still follow human-like patterns.

Copy-Paste Typing
Text is inserted without keystrokes. This behavior bypasses typing rhythm entirely and is flagged as copy and paste event.

Unnatural Typing
Shows irregular keystroke patterns, such as highly inconsistent timing, repetitive sequences, or unusually fast inputs that deviate from typical human behavior. These patterns may indicate automated responses, AI-assisted typing, or scripted entries—making them strong indicators of non-human activity.

​
BAS Classification System

ReDem uses AI and proprietary algorithms to assign each response to one of the following categories:

  • Natural – Genuine human input
  • Unnatural: Potential automation, AI typing, or scripting
  • Copy-paste: No natural typing activity detected

​
Scoring system

BAS produces a score from 0 to 100:

  • > 50 → Indicates natural or human-like typing
  • < 50 → Suggests unnatural or potentially automated input
  • 0 → Assigned when copy-paste behavior is detected
