Allow users to predict when an event will occur. Tap into the collective wisdom of your readers to predict future events and chart those predictions.
PredictWhen is a plugin that allows WordPress blog owners to tap into the wisdom of crowds and poll predictions from their readers as to when an event of their choosing will occur. The plugin calculates the average of these predictions and presents a date, or date range, when the event is likely to occur. It also generates a graph to chart the spread of predictions in a graphical format.
Example predictions created by blog owners might be:
PredictWhen has been built to harness the 'wisdom of crowds'.

Once an event has occurred, the question is closed and the actual date the event happened is entered. The chart then shows the actual event date alongside the estimated date based on the submitted predictions.
This provides interesting data on the accuracy of the blog reader’s prediction.
If user registration is required for a question, then closing a question will assign a score to each users prediction based on the accuracy of their guess. To display a ranking table of users scores see the Usage section.
Blog owners can use the scoring functionality to incentivize their readers to make considered predictions or to include a competition mechanic for pride or prizes.
The plugin has a sister website PredictWhen.com which acts as a directory of published questions. An option within the plugin allows you to feature your question within the directory.
By listing your question on PredictWhen.com we aim to collate all the predictions powered by this plugin and give them more exposure. We list your question and link to the page on your blog where it is published, users must visit your blog to make their prediction.
The plugin provides the ability for logged-in users to submit their own question to the administrator for consideration.
Questions submitted by users are subject to approval by the blog administrator.
You can invite your readers to suggest their own questions or choose not to promote this feature.
