Projects (in no particular order)


An open acccess, free-to-publish, data-sharing, open peer review metajournal right now focusing on differential psychology but we will expand.

The Worldwide Megadataset
Huge dataset of hundreds of international data. Opensourced.

Lyddansk - RSS (Danish)
My proposed reform for Danish orthography. The site also includes various discussions of parts of the proposal and other possible reforms.

DAT - Dictionary Analysis Tool
Tool useful for analyzing language, particularly orthographies.

Legaliser.nu - RSS (Danish)
A website arguing for the legalization of all psychoactive drugs in a more academic and serious way than most such websites do.

A collection of introductory reading and infographs to share with people for a very quick introduction to something.

Statistiske forudsigere for kriminalitet blandt danske indvandrergrupper
Kriminalitetshyppigheder blandt indvandrergrupper blev forsøgt forudset ud fra forskellige variable om gruppernes hjemlande. Islam, IQ, og højde viste sig at være rigtig gode forudsigere. I samlede multiple regression-modeller var R omkring .8, som ellers er uhørt højt i social science.

Omtale af ekstremisme i danske medier i årene 2003-2013: en kvantitativ analyse
"Grundet diskussioner i den offentlige debat om hvorvidt journalister er røde eller ej, og om dette påvirker deres arbejder, og i hvilken grad, så blev det klart at der var brug for en kvantitativ analyse af emnet.  Da det blev påstået at medierne oftere omtaler højrefløjsekstremisme og nedtoner venstrefløjsekstremisme, så var det en god mulighed for at undersøge emnet. En undersøgelse af mediernes omtale af hhv. højre-, venstrefløjs, og muslimsk ekstremisme vha. Infomedia viste at højrefløjsekstremisme meget oftere blev omtalt end venstrefløjsekstremisme eller muslimsk ekstremisme. Resultatet blev diskuteret som muligt tegn på at journalisternes politiske overbevisninger har en effekt på hvad de skriver og om hvad de skriver."

Emil's PDF library
A friend of mine discovered a powerful php command that can search a webserver for files, and create a list of links to those files. Naturally, we used this to search the webserver for PDF files, thus creating an automatically updated electronic library (his library).
If you encounter a dead link, it is because the script cannot handle certain symbols (like the apostrophe). Usually one can work out the true link by guessing which symbol it is that the script can't handle.

ProofTools - PT (Off-site) (English)
A tool for automatically drawing tree proofs for logic (standard propositional and standard first-order predicate. Programmed by Laird Shaw (link is to his website).

Logic (currently dead) (English)
Various information about how to manually draw truth tables and the like. Some of it based on the works of Norman Swartz and Ray Bradley. The idea is that I will have written an entire textbook to logic at some point. Every cool logician writes his own textbook, you know. Maybe that's why there are so many of them!

XKCD Wikipedia script
A small script that automatically tests how long it takes for a given Wikipedia page to get to "Philosophy". Has a lot of statistics as well for later analysis.

Meritocracy study 2011 (Danish/English)
A study of the effects of weighting votes differently for different people according to highest attained education level.

30 the dice game study (English)
An analysis of the dice game called 30, with focus on figuring out the optimal strategy.

Taifho (board game) project (English)
The idea is to make an electronic version of the game that works in a browser. Also, the making of an AI that beats the best human players.

The structure of human knowledge - a cluster analysis of Wikipedia (English)
We want to study the overall structure of human knowledge. Wikipedia is a good proxy.

Gender differences in humor abilities - a data mining study
Some people have written that there are gender differences in humour abilities in humans. We want to test this using data mining from the world's best information source, Wikipedia!

Oversigt over grammatiske termer på latin, dansk, og engelsk (Danish)

Judging a book by its cover: Can you see how smart a person is from a picture? (English)

Aarhus Conlang Group (danish/english)
A group of linguistics students who are interested in constructed languages

DOTA2 LOL comparison project 2013
A scientific look at spammability in the two popular games.

Sex ratio of TED speakers
Sex ratios are interesting and useful for understanding human nature. The idea here was to check the sex of the TED talk speakers, who seemed to be mostly male. The hypothesis was confirmed, male% = 73%, with no notable change over time.

Hvor mange love og paragraffer er der i Danmark?

Man hører nogle gang om hvor svært det er at finde ud af hvad der er lovligt og hvad der ikke er lovligt. Det gøres særligt svært af de utrolig mange love vi har i landet. Jeg blev nysgerrig og ville vide hvor mange det egentlig drejer sig om. På retsinformation.dk kan man læse at der er hele 1437 forskellige danske love og bekendtgørelser (herefter bare kaldt "love"). Men da en lov kan indeholde et meget stort antal forskellige §er, så siger det ikke helt så meget om hvor ting der egentlig er man skal vide. I Danmark er det jo borgeres pligt at kende loven, i den forstand at man normalt ikke bliver frifundet fordi at man ikke kendte loven.

En metode blev fundet til at estimere antallet af §er i de danske love. Den blev brugt på to forskellige antageligvis repræsentative samlinger af hver 25 love. Resultaterne var nogenlunde de samme. Det blev estimeret at der findes omtrent 67,000 §er i de danske love.

Den danske indvandring: oprindelse og intelligens
Jeg har undersøgt hvilken IQ man ville forvente danske indvandre har ifht. deres oprindelsesland, og hvilken en de faktisk har if. tal fra Forsvarets sessionsprøve. Estimat: 89.9. Data fra Forsvaret: 86.3.

Effects of election thresholds?
What are the effects of election thresholds? Many countries have them, and people defend them rigorously, but there is very little research on them. So I did some myself.
