The system implemented for the Scottish Parliament is known to make it more difficult for any one party to win an outright majority, compared to the first-past-the-post system used for general elections to the UK Parliament in Westminster.<ref>{{cite web|url=http://www.scottish.parliament.uk/visitandlearn/Education/16285.aspx |title=Parliament in depth: Electoral System: Electoral system for the Scottish Parliament |publisher=Scottish Parliament |access-date=23 November 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141129054933/http://www.scottish.parliament.uk/visitandlearn/Education/16285.aspx |archive-date=29 November 2014 }}</ref> However, in [[2011 Scottish Parliament election|2011]], the [[Scottish National Party]] won 69 seats, a majority of four.<ref>{{cite news|title=Scottish election: SNP majority for second term|url=https://www.bbc.co.uk/news/uk-scotland-13319936|access-date=5 April 2017|work=BBC News|date=7 May 2011}}</ref>

In the first election for Scotland's new Parliament, the majority of voters surveyed misunderstood some key aspects of the difference there between the "first" (constituency) vote and the "second" (regional list) vote; indeed in some ways the understanding worsened in the second election.

The [[Arbuthnott Commission]] found references to first and second votes fueled a misconception that the constituency vote should be a first preference and the regional vote a second one.{{Citation needed|date=January 2015}}

To deal with the misunderstanding between "first" and "second" votes, the ballot for the 2007 Scottish Parliament election was changed as recommended by the Arbuthnott Commission. The British government announced on 22 November 2006 that the two separate ballot papers used in the previous Scottish Parliament elections would be replaced for the elections in May 2007 by a single paper,{{Clarify|reason=Is this referring to a change in ballot design or a switch to a [[mixed single vote]] system?|date=August 2024}} with the left side listing the parties standing for election as regional MSPs and the right side the candidates standing as constituency MSPs.{{Cn|date=August 2024}}
