Collaborative Forecasting Confidence Slider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing confidence levels from participants in collective intelligence systems are inaccurate and inconsistent, as participants struggle to express their internal confidence using numerical scales, and methods like waging are influenced by risk tolerance, leading to inconsistent and authentic expressions.
Innovation Solution
An interactive system using a graphical user interface with a slider that allows participants to adjust wagers across a range, employing a non-linear model to update reward values and generate forecast probability values, which motivates authentic and accurate confidence expressions by distributing capital between outcomes based on a novel Mean Square Difference scale.

Engineering Contradiction Analysis
1Measurement precision
If participants are asked to assign numerical probabilities or place wagers to express confidence, then confidence levels can be captured, but the expressions become inaccurate and inconsistent due to human difficulty with numerical scales and risk tolerance variations
Solution Approach 1:
The patent transforms the confidence expression parameter from numerical probability (0-100%) to a spatial position parameter (slider position on a visual scale). This changes how participants express confidence - instead of thinking in abstract numbers, they physically position a marker on a visual continuum, which research shows produces more accurate and consistent measurements of subjective confidence states.
Solution Approach 2:
The patent replaces the psychological/cognitive mechanism of numerical estimation with a motor-based spatial positioning mechanism. By substituting the mental task of assigning numbers with the physical action of moving a slider to a representative position, the system leverages spatial intuition which is more reliable and less prone to cognitive biases than numerical probability judgment.
2Ease of operation
If traditional linear wagering models are used, then simple reward calculations are possible, but risk tolerance variations cause inconsistent and inauthentic confidence expressions
Solution Approach 1:
The patent changes the reward calculation parameter from linear to quadratic (Mean Square Difference). This transforms the optimization problem participants face - instead of linear trade-offs that favor risk-averse or risk-seeking behaviors, the quadratic penalty for miscalibration creates symmetric incentives that authentically reflect confidence levels regardless of individual risk tolerance, while maintaining simple slider-based interaction.
3Productivity
If confidence values are aggregated across participants, then collective intelligence can be formed, but variations in risk tolerance and expression accuracy reduce the quality of aggregation
Solution Approach 1:
The patent implements confidence calibration using quadratic loss (Mean Square Difference) which transforms raw confidence expressions into calibrated probabilities. This mathematical transformation corrects for systematic over- or under-confidence tendencies in the population, producing aggregated forecasts with higher accuracy by weighting predictions according to their true reliability rather than raw expressed confidence.
Solution Approach 2:
The system provides feedback to participants about their calibration performance and adjusts weighting factors based on their historical accuracy. This feedback loop allows the aggregation mechanism to learn which participants provide reliable confidence expressions and weight their contributions accordingly, improving overall forecast accuracy while maintaining simple participant interaction.

AI summary
Systems and methods for amplifying the collective intelligence of networked human groups engaged in collaborative forecasting of future events having two possible outcomes. During a real-time session a computing device for each user displays a forecasting prompt and a dynamic user interface which includes a user-manipulatable marker moved by the user between a first limit and a second limit, where the position of the marker defines a forecasted probability of each possible outcome. The display also includes a first reward value and a second reward value, both of which are interactively responsive to the marker position. During a first time period, users manipulate the markers. After the first time period, a perturbation stimulus is displayed. During a second time period, users again manipulate the markers. After the second time period, a final group forecast is calculated based on the data collected during the first and second time periods.
