On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
A decision maker acquires and processes information about an uncertain state of nature by an inquiry: a contingent sequence of questions to be asked before a decision is reached. Inquiry is a costly activity, with the cost proportional to its length. We characterize optimal inquiries and uncover two behavioural implications associated with costly inquiry: attention span reduction (i.e., favouring shorter inquiries by focusing on a subset of decisions and assigning them different priorities) and confirmation bias (i.e., seeking evidence through inquiry to confirm a prior guess of which decisions are optimal). This framework can be used to understand prominent cognitive biases, such as framing and search satisficing in healthcare and tunnel vision in criminal investigation.
