How do you know what's true? - Sheila Marie Orfano

Overview

The video explains how Akutagawa’s short story “In a Grove” (early 1920s) and Kurosawa’s 1950 film adaptation “Rashomon” created the concept now known as the “Rashomon effect.”

In the story, a samurai is found dead, and multiple witnesses provide accounts that are each internally plausible but mutually inconsistent—even though they all implicate themselves. Because the audience receives no clear cue about which testimony is most accurate, the work highlights how truth can become uncertain and contested.

When the Rashomon Effect Emerges

The presenter outlines that the Rashomon effect typically arises when:

• No independent evidence can confirm what actually happened.
• Pressure for closure pushes an authority figure or system to identify a single “definitive” truth.

Core Argument

The video argues that the Rashomon effect challenges the belief in a single objective reality. Instead, it shows how perception is shaped by storytelling, bias, and limited information.

It then connects the idea to psychology and neuroscience:

• Memories are not simply recorded; they are reconstructed.
• Recall is influenced by prior experience and internal biases, including egocentric bias.
• Even accurate encoding can be altered by later information during recall—so people often remember a modified version rather than the original event.

Applications Beyond Fiction

The video broadens the concept beyond storytelling by highlighting contexts where disagreement can come from the same underlying data or from different perspectives:

• Science: Different teams using the same dataset and methods can still publish different results.
• Anthropology: Researchers’ backgrounds can strongly affect how they interpret communities (e.g., differing portrayals of the Mexican village of Tepoztlan).
• Public media: Reports on complex geopolitical events (e.g., a 2015 US–Arab States security summit) can vary drastically—describing the same event as either a success or a failure.

Philosophical and Practical Questions

The video frames the Rashomon effect as raising broader issues, such as:

• What counts as “truth” when objective agreement may not exist?
• What can differing accounts reveal about the people and context involved?
• How should groups make decisions when members hold different information and biases?

While acknowledging there may be no definitive answers, the video concludes that the lasting value of Akutagawa’s story lies in recognizing and embracing ambiguity rather than forcing certainty.
