Framing to reduce present bias in infrastructure design intentions

Area of Science:

• Behavioral Economics
• Infrastructure Design
• Cognitive Psychology

Background:

• Present bias significantly influences decision-making, leading to suboptimal long-term choices.
• Infrastructure projects require long-term planning, making them susceptible to present bias.
• Understanding cognitive biases is crucial for effective project management and design.

Purpose of the Study:

• To investigate the impact of future- versus present-framed project descriptions on infrastructure design recommendations.
• To determine if temporal framing can mitigate present bias in professionals' design attribute selections.
• To identify practical strategies for improving long-term considerations in infrastructure development.

Main Methods:

• Randomly assigned 261 infrastructure professionals to receive either a future- or present-framed project description.
• Assessed recommended design attributes, including design life, community utility, and financial return.
• Employed statistical analysis to compare design attribute recommendations between the two framing conditions.

Main Results:

• Future-framed project descriptions resulted in significantly longer recommended infrastructure design life.
• Professionals in the future-framed group proposed a greater useful life to the community.
• Acceptable return on financial investment was also higher in the future-framed condition.

Conclusions:

• Temporal framing, specifically future-orientation, effectively reduces present bias in infrastructure design.
• A simple shift in project description framing can lead to more sustainable and beneficial long-term infrastructure planning.
• This finding offers a low-cost intervention applicable to diverse design and planning contexts.
