So there was a little bit of excitement yesterday as Jack Tame caught the National Party spreading misinformation on Q+A.

Chris Bishop was talking about dropping smokefree legislation and made the claim that there would only be one outlet in all of Northland.

Tame had done his research and said there was more likely going to be 35, which resulted in a classic caught out face from Chis Bishop, who stuck to his line and said he understood there was only going to be 1.

Unfortunately, Jack never asked him where that understanding came from. It came from the Prime Minister, who made the same claim earlier in the week. It was not questioned then, but there was more than enough time for the media to research it and wait for someone to use it again publicly. Which Bishop did and walked into a "gotcha" trap.

Now you've got opponents of the Government jumping up and down going on about the lying Government. Which is a wild over-exaggeration. The factoid was not crucial to their argument about black market trade and gang involvement in tobacco.

Mr Luxon did the right thing and came out and said his team made a mistake. He has urged them to fact check more before they give his Government talking points.

But it's still a thing- and a lesson not to be loose with facts.

As the Prime Minister noted last week about the Pubic Interest Journalism Fund - he stopped short of calling it bribery, but said there was a perception of it. And perceptions are dangerous. But not necessarily true.

The Prime Minister has already been caught out amplifying incorrect statistics through the campaign, so there is a perception that making up statistics is their modus operandi.

As the numbers of outlets was clearly and easily available, a perception could be made that policy is being formulated without sufficient research.

Chris Bishop used to be a tobacco industry lobbyist. Now caught using misleading statistics to support continued sales of tobacco there could be a perceptions of favour for former employers- which is a bad look.

The Prime Minister could be perceived to be in thrall of the Dairy Owners Association who have argued against prohibition, because it would wreck dairy profitability.

The Labour Government found out that perceptions stick. Considering this new Government is only a week old, they might want to learn that lesson fast.
