Abstract
The study explores the political careers of backbenchers in UK Parliament, seeking to understand why some progress and others do not. The survey experiment looks in particular at the extent of knowledge each politician has about his/her peers, in the aim of testing the hypothesis that Parliament is (in some sense) actually an information-weak environment.

Experimental Design
Experimental Design
MP respondents will be randomly allocated the name of another MP to answer questions about. The accuracy of the answers will reflect how well one MP knows another (and thus how prominent the other one is).
Experimental Design Details
Specifically, the randomly assigned MP will either be a man/woman and a winner or loser of the private members' bill ballot. The purpose is then to test whether it is ballot winners that have become more prominent/well known in Parliament.
Randomization Method
Randomization done in office by a computer. Stratified by party-gender (giving 6 strata). Rule-based re-randomization until minimum p-value from pre-set balance regressions is greater than 0.1.
Randomization Unit
Individual-level (MP-level).
