Selection and Stratification ServicesSelection & Stratification

The Sortition Foundation offers bespoke selection and stratification services for your deliberative event. We realise that finding a random, representative sample of people can be a challenge so we have learnt from the best — and now offer to bring the world's best practice selection process to the UK, Australia and the rest of the world.

Software & Training

We have developed two pieces of open-source software that we are happy to share and offer training and support to use.

  • StratifySelect: this is our core software that performs the random stratified selection, to match specified demographics, from a pool of registrants. The selection is designed to be "as fair as possible" as will be outlined in a forthcoming academic paper being written by Ariel Procaccia from Harvard University and his colleagues and students.
  • GroupSelect: this software can be used to allocate citizens' assembly participants pseudo-randomly to a set of groups (usually tables) during deliberation, to maximise diversity in each group, and to maximise interactions between people during differing assembly sessions. It also features a range of advanced options such as: unlimited number of possible diversification fields, prioritisation of fields, clustering, and manual allocations.

To find out more about either of these pieces of software please contact us.

Statement of Independence

 Our core aim is for these processes to have the highest possible level of legitimacy and therefore a core principle is to maintain independence with regards to the topics and issues addressed in citizens' assemblies and deliberative events. Our focus is on the recruitment and selection process itself, and we use open-source algorithms documented in peer-reviewed journals to perform every stratified random selection, ensuring they are all "as fair as possible." Each selection is not, and cannot be, influenced by the position any organisation takes about any particular issue and our staff and directors are committed to making sure this continues to be the case.
