Summary
The Black Death impacted mortality risk differently based on age and sex. Middle-aged males faced higher mortality, highlighting how pandemics interact with existing social and biological vulnerabilities.
Area of Science:
- Paleopathology
- Bioarchaeology
- Historical Epidemiology
Background:
- The Black Death (14th century pandemic) disproportionately affected populations, but demographic influences on mortality risk remain incompletely understood.
- Previous research often examined age or sex independently, lacking a nuanced understanding of intersectional vulnerabilities.
Purpose of the Study:
- To investigate how demographic factors, specifically the intersection of age and sex, influenced mortality risk during the Black Death.
- To test the hypothesis that younger males faced a compounded mortality risk.
Main Methods:
- Analysis of skeletal data from seven medieval London cemeteries using the Wellcome Osteological Research Database (WORD).
- Logistic regression and Kaplan-Meier curves assessed plague mortality risk, controlling for cemetery type, context, and frailty markers.
- Missing data were imputed using missForest.
Main Results:
- The interaction of age and sex revealed that males aged 52-64 had a statistically significant protective effect, indicating lower odds of plague mortality.
- The presence of frailty was a significant factor in mortality risk.
- Cemetery type (layperson/religious) and urban/rural context were not statistically significant predictors.
Conclusions:
- The Black Death amplified existing biological and social vulnerabilities, with middle-aged males exhibiting higher mortality risk.
- Biological susceptibility appeared to outweigh social disadvantage in shaping plague mortality.
- Pandemics are influenced by social inequalities, offering insights into current health disparities.

Social Scripts
10.2K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...
