There are six dimensions to this scale: Relativism, Religiousness, Integration, Theism, Externality–Internality, and Externality Size. Each dimension has 6 possible values on a scale of 0–5, from least to most intensity.

  1. Relativism is a measure of how relative one sees the world around them.

    (5) Strong Relativist
    4) General Relativist
    3) Relative Binarist1
    (2) General Binarist
    (1) Strong Binarist
    (0) Unarist2

  2. Religiousness is a measure of how strongly one experiences religion in their daily life.

    (5) High Intensity, Frequent
    4) High Intensity, Infrequent
    3) Medium Intensity, Neither Frequent nor Infrequent
    (2) Low Intensity, Frequent
    (1) Low Intensity, Infrequent
    (0) Nonexistent

  3. Integration is a measure of how much one integrates religious experience into one’s daily life.

    (5) Always
    (4) Most of the time
    (3) Half of the Time
    (2) Sometimes
    (1) Occasionally
    (0) Not Applicable

  1. Theism is a measure of how strongly one believes in a deity.

    (5) Very Strongly
    4) Strongly
    3) Somewhat
    (2) A Little3
    (1) Very Little4
    (0) Not at All5 / Not Applicable6

  2. Externality–Internality is a measure of how strongly one prefers experiencing religion through external sources (i.e. with other people/organisms/etc.) vs internal sources (i.e. introspection, solitary activities).

    (5) Very Highly External
    (4) Highly External
    (3) Equally External & Internal
    (2) Highly Internal
    (1) Very Highly Internal
    (0) Not Applicable

  3. Externality Size is a measure of how many external sources (i.e. other people/organisms/etc.) one is typically involved with during religious externalities.

    (5) Very Large Group
    4) Large Group
    3) Moderately Sized Group
    (2) Small Group
    (1) Very Small Group
    (0) Not Applicable


Graphing the Data

After surveying someone with these questions, one can then plot the results on a radar chart. This chart is shown below:

Berry Religiosity Index (BRI) + Border

Here’s an example using my own religious data:

Dimensions Score
Relativism 5
Religiousness 1
Integration 1
Theism 1
Externality–Internality 1
Externality Size 0

BRI (Sarah Lasair Berry) + Border


1 Someone who is binarist in some situations but relativist in others.

2 Someone who believes either that everything is totally good or everything is totally bad.

3 E.g. “Strong” Agnostic (“I am unsure if a deity exists, and it is not possible to know.”)

4 E.g. “Weak” Agnostic (“I am unsure if a deity exists, but it may become possible to know in the future.”)

5 E.g. Atheism

6 E.g. Nontheism
