The Flesch–Kincaid readability educational test are designed to indicate how difficult a text is to
understand. The test uses word length and sentence length to calculate a readability score. The
results provides information on what level of education a reader needs to understand the text and it
can also provide some information about the education level of the writer of the text. For example,
if a text is best understandable by a college student it is likely to assume that the writer also
have at least a college education. The sore ranges from 0-100 where 100 is very easy to read and 0
is very hard to read.

An important part of an individual's self-concept is shaped by our relations with others.
Being a
part of a group, is a basic human need fundamental for survival and therefore group
identification and the concept of social identity are two important components in explaining
what motivates an individual’s actions. Examining use of pronouns can thus inform us how
people
consider themselves in relations to others, groups as well as individuals.
A high score on the use of outgroup references (third person plural) indicates that the
writer of
the text have a tendency to see boundaries between groups and defines him/herself in terms
of
in/out-group. A low score on social connection indicates social isolation. A high use of
first
person singular (I) reflect self-focus can be compared to a high use of fist person plural
(we)
reflecting group-focus.

The warning behavior fixation is defined as any behavior indicating a nearly pathological
preoccupation with a person or a cause. This category of warning behavior is directly related to
or indicative of the possible target of an action. To observe fixation Dechefr provides the 10
most frequently used words and the 10 most frequent collocations phrases. A collocation is two
words that often go together. Some collocation examples are "pay attention", "fast food", "make
an effort", and "powerful engine". The most frequently used words and collocations may give
insights to if the writer is fixated with a person or a cause.
The affiliation score provides information on what kind of ideology or subculture the writer of
the text could be influenced by.

Summary
The General Risk Score is automatically generated based on all indicators in Dechefr. The score is fixed and, thus, cannot be changed by the user. Scores range between 0 (no risk) and 100 (maximum risk) and reflect three risk levels:
- Low risk: no or few indicators of violent intention and action are present
- Moderate risk: some indicators of violent intention and action are present
- High risk: several indicators of violent intention and action are present

The analyst can (and should) always verify the computer generated assessments manually.
