Most bad decisions aren’t about intelligence; they’re about bias.

Groupthink = harmony over honesty. We go along to get along.

Effective leaders invite challenge, not just agreement.

Most bad decisions aren’t about intelligence; they’re about bias.

Confirmation bias = seeking evidence that proves us right and ignoring what doesn’t.

Effective leaders invest effort into testing their thinking, rather than defending it.

Most bad decisions aren’t about a lack of intelligence; they’re about bias.
Take recency bias: we overweigh what just happened and ignore bigger patterns.
Effective leaders zoom out and look for trends, not moments.

Not a portage at all, but the Auckland city 'Coast to Coast' trail from the Manukau to the Waitematā. Fun to run anyway.

The Whau Portage. From Green Bay in the south to the Whau River in the north. 2.96km. Interestingly, most portages are really really short (as little as 1km long) so I've added a bit extra onto the runs to make them more of a workout.

Not only would running the portages help me to get to know the history of the city a bit better, but they are also (by design) typically fairly flat. Being interested in history and quite lazy, both of these things appealed to me.

I'm a runner and enjoy finding trails that make exercise a bit more interesting than just pounding the pavement. When a new section of walkway along one of these portages (near where I live) opened recently, it got me thinking.

A portage (as I'm sure you know) is a low crossing between two bodies of water. Here, this typically means a route historically used by Māori to transport waka from one coast to the other to avoid (long and often arduous) detours.

I live in Auckland (Tāmaki Makaurau) which is perched on an isthmus between the Manukau and Waitematā harbours in Aotearoa New Zealand. Lately I'm become a little bit obsessed with the city's traditional portages.

Most bad decisions aren’t about intelligence; they’re about bias.

Anchoring bias = the first thing we hear about something often sets our reference point even when later information disproves it. First impressions count.

Effective leaders reset the anchor before deciding.

Teaching as Inquiry: Bias and the Brain
Teaching as Inquiry: Bias and the Brain Common cognitive biases and how they can impact on the gathering and analysis of data to inform teaching.

What are the six cognitive biases that most typically undermine the effectiveness of teacher reflection and inquiry? Another way to consider the question is to ask 'Who sabotaged my thinking?' Here's a chunk from my latest webinar exploring the main culprits: www.youtube.com/watch?v=7Skd...

Our next webinar looks at the cognitive biases that often limit human decision making. More importantly, it also looks at how we can limit the impact those biases have on our ability to analyse situations and take action.
