Consider the amount of open source statistical software available at the Comprehensive R Archive Network (CRAN).
Packages such as car, psych, lavaan, OpenMx were developed by and for psychologists. They have more than 5-10k downloads per day.
R is an open source tool for developing tools.

I write my own code for the psych package so that I can learn new statistics. My knowledge of stats/psychometrics has increased as I have added new functions to psych. Some of the functions are to handle data sets that are unusual in their structure and conventional algorithms will not work.I
