Forecast a multiple-choice question

Forecast how likely each option of a multiple-choice question is, replacing your current forecast. Every option needs a chance, and they add up to 100%.

Inputs

QuestionquestiontextRequired: The question's id or link: the number in metaculus.com/questions/<id>/, or the whole link. Search questions returns it as post_id.
Probabilities (%)probabilitiesobjectRequired: Each option's chance as a percent, adding up to 100: an object such as {"Democratic": 55, "Republican": 44, "Other": 1}, text such as 'Democratic: 55, Republican: 44, Other: 1', or a list in the options' order. Each option needs 0.1 to 99.9.
Subquestionsubquestiontext: Only for a page holding several questions. In a group, the row's label (such as 2030) or its question_id; in a conditional, 'yes' for the question if the condition resolves Yes or 'no'. A link copied from a group row picks it already.

Forecast a numeric or date question

Forecast a numeric, discrete or date question from your 25th percentile, median and 75th percentile, as on Metaculus's own table input, replacing your current forecast. The distribution is built on the question's own scale and standardised the way Metaculus documents, so it is accepted. A full CDF can be sent instead.

Inputs

QuestionquestiontextRequired: The question's id or link: the number in metaculus.com/questions/<id>/, or the whole link. Search questions returns it as post_id.
Subquestionsubquestiontext: Only for a page holding several questions. In a group, the row's label (such as 2030) or its question_id; in a conditional, 'yes' for the question if the condition resolves Yes or 'no'. A link copied from a group row picks it already.
25th percentilepercentile_25text: The value you think there is a 25% chance of landing below, in the question's units. For a date question, a date such as 2027-06-30.
Medianmediantext: The value you think is as likely to be beaten as not. Give at least one of the three percentiles.
75th percentilepercentile_75text: The value you think there is a 75% chance of landing below.
Chance below the range (%)chance_belownumber: Only when the range is open at the bottom: the percent chance the outcome falls below it. Defaults to 0 (then at least 0.1% is kept there).From 0 to 100.
Chance above the range (%)chance_abovenumber: Only when the range is open at the top: the percent chance the outcome falls above it. Defaults to 0 (then at least 0.1% is kept there).From 0 to 100.
CDF (advanced)cdflist: Instead of the percentiles: a full cumulative distribution from another tool, 201 values from 0 to 1 (the question's inbound_outcome_count + 1), sent as it is.
Withdraw automatically atwithdraw_atdate and time: Withdraw the forecast on its own at this time. Leave empty for it to stand until you change it or the question closes.
