Causality in Epidemiology

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Cause and Effect

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

The Availability Heuristic

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Criteria for Causality: Bradford Hill Criteria - II

Criteria for Causality: Bradford Hill Criteria - II

The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Criteria for Causality: Bradford Hill Criteria - I

Criteria for Causality: Bradford Hill Criteria - I

The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

Correlation and Causation

Correlation and Causation

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Summary

Humans use time to infer underlying causes of events, favoring recently observed causes. A "persistent" model best explains this temporal influence on latent-cause inference.

Cognitive Science

Psychology

Background:

Human generalization relies on segmenting experiences and relating them to past events.
Temporal information's role in generalization and latent-cause inference is not fully understood.
Latent-cause inference models group experiences based on shared underlying causes.

Purpose of the Study:

To investigate how temporal information influences latent-cause inference in humans.
To evaluate different computational models of temporal influence on inference.

Main Methods:

Developed a novel task where participants inferred "strains" (latent causes) from "microbe" stimuli.
Compared human performance against a "persistent" model and other time-sensitive models.
Assessed the psychometric properties of the task and the best-fitting model.

Main Results:

Humans incorporate temporal information into latent-cause inference.
Recently inferred latent causes are more likely to be inferred again.
A "persistent" model, where causes have a probability of continuing, significantly outperformed other models.

Conclusions:

Temporal dynamics, specifically cause persistence, are crucial for human generalization.
The developed task and "persistent" model offer a way to quantify individual differences in inference.
Findings have implications for computational psychiatry and neuroimaging research.
