Unbiased selection of: “the best of…”

Discover an intriguing application of AI (specifically ChatGPT4) to eliminate any bias in awarding a prize for “the best of.” This approach serves as a trustless guarantee that the winner is selected not by us, but by ChatGPT, which operates independently of our influence.

We’ve adopted this method to identify “the best comment” among those posted on various SimFly social media accounts:

In essence, the AI generates a unique fingerprint (SHA256 hash) of the file containing the comments. It then selects the most insightful and constructive comment. To ensure transparency, we share publicly the link to the ChatGPT conversation. This allows everyone to verify that ChatGPT produced a specific fingerprint for a file and selected a comment from that file. We also provide a link to the file containing the comments, enabling anyone to confirm (by creating a SHA256 fingerprint of the downloaded file) that it’s indeed the file analyzed by ChatGPT.

HOW TO CALCULATE THE SHA256 HASH OF A FILE

This ensures the file provided to ChatGPT is exactly the one available for download (see below).

In Windows with PowerShell:

  1. Open Powershell.
    Click Start, type PowerShell, and then click Windows PowerShell
    Alternatively, from the Start menu, click All Programs, click Accessories, then Windows PowerShell folder, and finally Windows PowerShell.
  2. In PowerShell, type the command: Get-FileHash -Algorithm SHA256 C:\path\to\file.txt
    Replace “C:\path\to\file.txt” with the path to the file you have downloaded.
  3. Verify that the result matches the hash in the ChatGPT conversation
    (accessible via the link provided below).

In Linux and macOS with Terminal:

  1. Open Terminal.
    Click the Launchpad icon in the Dock, type Terminal in the search field, then click Terminal
    Or, in Finder, open Applications > Utilities folder, then double-click Terminal
  2. In Terminal type this command: shasum -a 256 /path/to/file.txt
    Replace “/path/to/file.txt” with the path to your downloaded file
  3. Ensure that the result matches the hash in the ChatGPT conversation
    (accessible via the link provided below).
