Groupthink arises from the desire of a group to maintain harmony and consensus. Groupthink can reduce the diversity of ideas and opinions — people can seek to avoid conflict, or avoid expressing unpopular views, and end up thinking down the same path. When psychological safety is low and people feel they may experience disapproval, particularly from people with higher ranking or status within the group, groupthink can get worse.

It can be uncomfortable to express opinions different from a group. Perhaps you remember that feeling when a teacher asked a question in class and if everyone raised their hand to one answer it wasn't always easy to be the only hand up for a different one.

Fortunately, there are some solid ways to minimise the tendency to groupthink. These include:

Generating ideas separately before coming together — can be effective remotely too

Increasing psychological safety so everyone feels comfortable expressing contrarian views

Establishing the norm of a shared work product rather than individual credit/blame

Groupthink

A pleonasm is the use of redundant words, often in established phrases or idioms.

I tried to write something, but it's hard to beat this excellent excerpt by the comedian George Carlin from When Will Jesus Bring the Pork Chops — spot the pleonasms:

"My fellow countrymen, I speak to you as coequals, knowing you are deserving of the honest truth. And let me warn you in advance, my subject matter concerns a serious crisis caused by an event in my past history...At that particular point in time, I found myself in a deep depression, making mental errors which seemed as though they might threaten my future plans. I am not over-exaggerating.

I needed a new beginning, so I decided to pay a social visit to a personal friend with whom I share the same mutual objectives and who is one of the most unique individuals I have ever personally met. The end result was an un­expected surprise. When I reiterated again to her the fact that I needed a fresh start, she said I was exactly right; and, as an added plus, she came up with a fi­nal solution that was absolutely perfect.

Based on her past experience, she felt we needed to join together in a com­mon bond for a combined total of twenty-four hours a day, in order to find some new initiatives. What a novel innovation! And, as an extra bonus, she presented me with the free gift of a tuna fish. Right away I noticed an immedi­ate positive improvement. And although my recovery is not totally complete, the sum total is I feel much better now knowing I am not uniquely alone.”

Other examples people have shared with me include one-year anniversary, and revert back. The other day, I wrote "new discoveries", which Grammarly helpfully suggested shortening to "discoveries."

Pleonasm

You know that time when you couldn't concentrate at all because of someone having a phone conversation right next to you? It's the trouble with a halfalogue. Hearing only one side of a conversation, it turns out, can be more distracting than hearing the whole dialogue. This might stem from the unpredictability of the conversation — our brains working overtime to connect the dots and uncertain what's coming next.

Halfalogues were investigated in a paper by Lauren Emberson and coauthors: Overheard Cell-Phone Conversations: When Less Speech Is More Distracting. The distraction potential of halfalogues could have more serious impacts on a driver from a passenger's phone conversation in the back.

A halfalogue is a nice extension of the dialogue and monologue.
