Reference excerpt

The Portraits of American Life Study (abbreviated PALS, originally known as the Panel Study of American Religion and Ethnicity) is a panel study focusing on religion in the United States, particularly as it relates to racial and ethnic diversity. The study's first wave of data collection took place in 2006, and surveyed 2,610 people. In 2008, the researchers attempted re-contact with the 522 original respondents who attended religious services several times per year despite not being a member of a religious congregation. The original 2006 study was led by sociologists Michael Emerson of Rice University and David Sikkink of the University of Notre Dame. In 2012, the researchers surveyed exactly the same people they originally surveyed six years earlier. The 2012 survey showed that a significantly higher percent of Americans (58%) respected all religions equally than did in the original 2006 survey (one-third). In 2016, University of Oklahoma sociologist Samuel Perry analyzed data from the PALS and found that people who watch pornography at least once a week are more likely to be religious six years later. A 2013 Brandeis University analysis of the PALS found that people who consider religion important in their lives are more likely to make decisions based on their religion.

Worked examples

Example 1 — a first encounter with Portraits of American Life Study

Start with the simplest possible case. Write down what Portraits of American Life Study claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Portraits of American Life Study before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Portraits of American Life Study ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Portraits of American Life Study

In research: Portraits of American Life Study appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Portraits of American Life Study in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Portraits of American Life Study is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cohort studies, Surveys (human research), so understanding it makes those chapters shorter.
In everyday life: Look for Portraits of American Life Study outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
