Societal Effects

  • This phenomenon has already revolutionised biology.
    • Large scale data acquisition and distribution.
    • Transcriptomics, genomics, epigenomics, ‘rich phenomics’.
  • Great promise for personalized health.

Societal Effects

  • Automated decision making within the computer based only on the data.
  • Subjective biases need to be better understood.
  • Particularly important where treatments are being prescribed.
    • Interventions could be far more subtle.

Societal Effects

  • Shift in dynamic:
    • from direct human-data to indirect human-computer-data
    • modern data analysis is mediated by the machine
  • This change of dynamics gives us the modern and emerging domain of data science

The Great AI Fallacy

There are three types of lies: lies, damned lies and statistics

In practice …

  • There is a lot of evidence that probabilities aren’t interpretable.

  • See e.g. Thompson (1989)

Number Theatre

Data Theatre

}{The focus so far has been on reducing uncertainty to a few representative values and sharing numbers with human beings. We forget that most people can be confused by basic probabilities for example the prosecutor’s fallacy.}{anne-llm-conversation}

In practice …

  • LLMs are already being used for robot planning Huang et al. (2023)

  • Ambiguities are reduced when the machine has had large scale access to human cultural understanding.

Inner Monologue

Behind the Eye

Later in the 1940's, when I was doing my Ph.D. work, there was much talk of the brain as a computer and of the early digital computers that were just making the headlines as "electronic brains." As an analogue computer man I felt strongly convinced that the brain, whatever it was, was not a digital computer. I didn't think it was an analogue computer either in the conventional sense.

Human Analogue Machine

Counterfeit People

  • Perils of this include counterfeit people.
  • Daniel Dennett has described the challenges these bring in an article in The Atlantic.

Psychological Representation of the Machine

  • But if correctly done, the machine can be appropriately “psychologically represented”

  • This might allow us to deal with the challenge of intellectual debt where we create machines we cannot explain.

Conclusions

  • HAMs change how we share ambiguous information.
  • We need to think about how that effects our sharing of proabilities.

Thanks!
