Tasmanians who vote for the established parties tend to be smarter than those who don't, new analysis suggests.
The analysis showed a clear pattern in all five electorates in the 2018 state election that Greens, Liberal and Labor voters were more likely to fill out voting papers correctly than people who voted for smaller parties or unaligned independents.
The analysis is based on Tasmanian Electoral Commission figures covering voters who messed up their votes in the 2018 state election after correctly giving their number one vote to a candidate.
They then either repeated numbers or omitted numbers between their number two votes and their number five votes.
It meant their votes were not able to be counted, with the TEC classing them as apparently unintentional informal votes, along with the votes of those who put ticks and/or crosses next to candidates' names or who numbered some candidates, but did not nominate a number one.
The analysis assumes intelligence (or lack of) was a significant factor.
It showed Greens voters in all five electorates were least likely to mess up their ballot papers after correctly nominating a number one candidate.
Greens voters statewide who did that equated to just 0.54 per cent of the party's total formal votes.
Liberal voters were next best on that measure (0.63 per cent), followed by Labor voters (0.74 per cent).
Jacqui Lambie Network voters were next (2.18 per cent), although they performed much better in Ms Lambie's home base, Braddon (1.08 per cent).
Voters for ungrouped independents (2.6 per cent), Shooters, Fishers and Farmers (2.75 per cent) and T4T - Tasmanians 4 Tasmania (4.25 per cent) were the most likely to mess up their votes.
Analysis covering all apparently unintentional informal votes from the election suggested Braddon voters were Tasmania's least intelligent.
Southern electorate Franklin looked the smartest.
Clark (formerly Denison) was the second smartest, followed by Bass and Lyons.
The number of voters who apparently unintentionally voted informally was equal to:
- 1.90 per cent of all formal votes in Franklin;
- 2.33 per cent in Clark;
- 2.59 per cent in Bass;
- 3.04 per cent in Lyons; and
- 3.22 per cent in Braddon.
While the analysis assumes intelligence is a significant factor in whether people who try to vote manage to correctly fill out voting papers, other factors would include literacy and, possibly, poor eyesight and rushing.
The voters discussed are different from those who do not try to lodge valid votes.
