Creating diversity and awareness in the TYPO3 community

Sociological and psychological concepts


Wikipedia article

A community or group is considered diverse if its members are different, particularly concerning the following aspects:

  • gender identity ((cis-)male, (cis-)female, genderqueer/nonbinary, transgender …)
  • sexual orientation (heterosexual, homosexual, bisexual, asexual …)
  • enthnicity (black, hispanic, asian, caucasian …)
  • age (young, old …)
  • religion (Islamic, Christian, atheist, Hindu …)
  • physical abilities (blind, deaf, mute, wheelchair-bound, red-green-blind, able-bodied …)
  • physical health
  • attractiveness
  • mental health (autistic, having axieties, having depression, …)
  • intelligence
  • socioeconomic background (having grown up with lots of or little money, having had books around as a child, having a/no university degree, …)

There are studies that show that diverse team are more productive and create products that appeal to (and work for) larger target groups.


Wikipedia article

Inclusion means removing barriers and providing help for people with disabilities (in the narrower sense), removing barriers for people that are underrepresented in a group/event, and even making the group/community/event openly welcoming to underrepresented groups so they can integrate easily.

Being inclusive is necessary for improving diversity (although not sufficient in itself).


*Phobias (islamophobia, homophobia, …) mean that a person is hateful of a certain group or has prejudices towards this group.

There are also phobias in the psychological sense (agoraphobia, arachnophobia, …). Those are not relevant in this context.


*isms (sexism, racism, …) refer to actions of structures that work against members of certain identity groups. (There is no really clear border between *phobias and *isms, though.)

article about systemic sexism

Hostile and benevolent sexism

Wikipedia article

Sexism (the notion that persons of one gender are less worth than other genders) comes in two flavors:

Hostile sexism refers to the notion that persons of one particular gender are incompetent, stupid etc., while benevolent sexism refers to the notion that members of a certain gender need to be protected etc. because they are weaker, nobler etc.


Wikipedia article

Ableism refers to the notion that able-bodied persons are "normal" and that the needs of disabled people are not important.


Wikipedia article

Microaggressions ("death by a thousand cuts") describes a situation where a person experiences a huge amount of relatively small hostile/aggressive acts, which in the sum still can make a situation intolerable and drive the person away from the group/situtation.

The persons committing the microaggressions usually see their behavior as "no big deal".

Cognitive biases

Wikipedia article Online self-test for biases

A cognitive bias refers to tendencies to see a situation in a non-subjective or non-rational way without being aware of this.

Confirmation bias

Wikipedia article

Confirmation bias refers to the tendency to recognize facts that confirm one's opinion while ignoring facts that contradict one's opinion in order to avoid cognitive dissonance.


Wikipedia article articla about privilege

Privilege refers to "playing the game of life at an easier difficulty setting" due to being born (or having grown up) with certain properties, for example:

  • able-bodied
  • white
  • cis-male
  • heterosexual
  • intelligent
  • having wealthy parents and a good education

Being privileged in certain aspects does not mean "having a good life", but it can lead to a tendency to generalize this "easier setting" concerning other people and dismissing their experiences.

The statement "check your privilege" is used to remind someone that they might be privileged, and that other people might have had vastly different experiences.
