The author’s daughter’s tool kit

A while back, Decision Science News put out a call on the Society for Judgment and Decision Making email list looking for “tools, methods to improve decision making, outcomes, and information communication / visualization”:

I’m interested in learning about tools and methods people in this community have created to improve decision making, decision outcomes, and information communication / visualization. It would be good to have examples of things that are a) finished, codified b) tested for effectiveness. Bonus points if they are field tested and/or tested for long-term retention

This would include things like:
* Training programs incl. games, videos, procedures, tutorials
* Decision aids, calculators
* Elicitation techniques (e.g. SPIES, …)
* Changes in information format (e.g. frequency formats, …)
* Policies, procedures (e.g. Save More Tomorrow, …)
* Feats of choice architecture (e.g., reordering, ….)

To make the resulting list more useful to the community, it might be wise to structure your submissions like this:

These tools are similar to the Distribution Builder (*) tool for eliciting probability distributions

DECISION TIME LIMITS

Ian Krajbich writes “By imposing per-decision time limits, we help people divert time from difficult unimportant decisions to easier important ones.”

Effectiveness test result: Time-constrained subjects achieve better objective outcomes (higher earnings) when they have per-decision time limits, compared to when they are left to allocate time to decisions on their own.

BALANCE BEAM AID FOR INSTRUCTION IN DIAGNOSIS

Rob Hamm writes “The log odds formula for combining multiple independent diagnostic cues corresponds to the formula for combining the impact of equal weights (and helium balloons) placed at different positions on a balance beam. We constructed a demonstration for one medical diagnosis domain (acute chest pain).”

Effectiveness test result: The math works if we make the naïve Bayesian assumption of independent impacts of different pieces of evidence. A small sample of medical students and faculty played with the program and found it reasonable.

PACE-O-METER TO IMPROVE PEOPLE’S ESTIMATIONS OF TIME-SAVINGS WHEN INCREASING SPEED

Eyal Pe’er writes: “An enhanced speedometer that presents, alongside regular speed information, the pace of minutes required to complete 10 miles/km at given levels of speed (http://journal.sjdm.org/12/121007/fig2.png)

Effectiveness test result: When asked to estimate time saved when increasing speed (at various levels) participants who received the “paceometer” were correct at an overall average rate of about 58% compared to less than 20% in the control conditions. In another study, similar results were found on driving behavior using a driving simulator.

PROSTATE CANCER TREATMENT DECISION AID
Maarten Cuypers writes: “Online tool with risk communication and values clarification exercise to support treatment selection in (early) prostate cancer patients”

Effectiveness test result: More knowledge, more value congruent treatment choices, though lower information satisfaction.

####################
SIMULATED EXPERIENCE

Emre Soyer writes “A simulation based on a model (e.g., regression), which allows decision makers to enter their inputs and sequentially observe (also graph and/or store) the estimated outcomes.”

Effectiveness test result: In different contexts, participants related easily with the tool, trusted their simulated experience more than their own analyses based on descriptions, and made more accurate judgments about uncertainties.

A DIAGNOSTIC SUPPORT SYSTEM (PROTOTYPE) FOR FAMILY PHYSICIANS

Olga Kostopoulou writes “A diagnostic support tool that integrates with the patient’s electronic health record, and presents physicians with diagnostic alternatives (according to patient age, sex, risk factors and current complaint) at the start of the consultation, BEFORE physicians elicit any further information from the patient.”

Effectiveness test result: Presenting family physicians with diagnostic alternatives early on, before eliciting any information themselves, increased diagnostic accuracy both in a study with computer-simulated patients, and in a study with standardised patients (actors).

Note: The tool is still at the prototype stage and has not been field-tested yet. It is based on an ontology of medical diagnostic concepts, and will be open source eventually.

####################
ANALOGICAL ENCODING

Aba Szollosi writes “We tested whether analogical encoding can foster the transfer from learning abstract principles to improving behavioral performance on a range of decision biases.”
Effectiveness test result: The method might be effective in eliminating biases on tasks where the violations of statistical principles are measured.

CHEMDECIDE
Richard Hodgett writes about a tool he created to structure complex decision problems. ChemDecide is a suite of software tools which incorporates three Multi-Criteria Decision Analysis (MCDA) techniques: Analytical Hierarchy Process (AHP), Multi-Attribute Range Evaluations (MARE) and ELimination Et Choix Traduisant la REalité trois (ELECTRE III). The software has been used for addressing decisions such as route selection, equipment selection, resource allocation, financial budgeting and project prioritization.

    This article is very comprehensive and gets full marks for its thoroughness and organisation.
    Would the writer recommend similar sources that are dedicated to general-purpose decision making at very senior levels of big organizations and very large entities?
