The Link Between Sharing Feelings and Fewer Life Regrets

Impact Bias

A cognitive bias where individuals overestimate how long they will feel negative emotions when something bad happens. This bias contributes to overestimating the risks of self-disclosure, as people forget that the 'cringy feeling' of embarrassment eventually subsides.

Galvanic Skin Response

A physiological measure of stress, typically indicated by how sweaty one's palms and fingertips become. Studies show that children who are more expressive in their faces and 'let it out' are less physiologically stressed, suggesting a link between outward expression and reduced internal stress.

Disclosure Flexibility

The skill of adapting one's level of openness to different contexts and relationships. Highly skilled revealers can shift from being extremely open with a life partner to being reserved and guarded in a competitive professional setting, demonstrating self-awareness and strategic intent.

Mind Reading Expectations

The implicit belief that others, especially close partners or friends, should instinctively know how you feel or what you need without explicit communication. This often leads to communication breakdowns and resentment in relationships because people stop asking questions and revealing their inner states.

Emotions Wheel

A tool designed to help individuals refine and articulate their feelings by expanding their emotional vocabulary. It starts with broad categories like 'good' or 'bad' and then branches out to more specific adjectives, aiding in self-awareness and effective communication of one's inner state.

?
Why do people often prefer keeping secrets or withholding information?

People tend to fixate on and overestimate the risks of revealing, such as potential embarrassment or negative consequences, while underestimating the costs of staying silent and the benefits of disclosure.

?
What are the physiological and psychological costs of keeping secrets?

Keeping secrets leads to rumination, increased mental load, and can temporarily decrease IQ. Chronically keeping secrets is linked to lower well-being, more frequent illness, and can manifest as passive aggression or avoidance.

?
How does putting feelings into words benefit mental well-being?

Translating feelings and thoughts into language engages the prefrontal cortex, the logical part of the brain, and imposes a story structure. This process creates a sense of certainty and concreteness, reducing the anxiety caused by swirling, uncertain thoughts.

?
What is the most helpful response when someone is sharing something difficult?

Validation, such as saying 'I hear you' or 'That sounds like it's really hard,' is the most comforting and effective response. It makes the person feel understood and helps them cope, often more so than offering advice or trying to emphasize the positive.

?
How can one improve their self-disclosure skills?

Start by becoming aware of the many daily opportunities for disclosure. As a rule of thumb, try to go one layer deeper than you ordinarily would in a conversation, and then ask an appropriately probing question to your conversation partner.

?
When is it appropriate for a leader to reveal a weakness?

Leaders can reveal minor weaknesses, such as being 'a little nervous about public speaking' or experiencing a dry mouth, to build trust without diminishing perceived competence. However, revealing severe issues like 'full-on panic attacks' can undermine competence.

?
What is the 'Ben Franklin upgrade' for making disclosure decisions?

The 'Ben Franklin upgrade' encourages considering all four quadrants of a decision: the pros and cons of revealing, and the pros and cons of not revealing. This comprehensive approach helps overcome the natural tendency to only focus on the risks of disclosure.

?
Why do long-term relationships sometimes lose intimacy?

In long-term relationships, people often develop an overconfidence in their knowledge of their partner, which massively outsizes their actual understanding. This leads them to stop asking questions, stop being curious, and stop revealing, causing a decline in intimacy.

1. Embrace Self-Disclosure for Well-being

Actively engage in self-disclosure, as it is intrinsically rewarding, activating pleasure centers in the brain, and can reduce physiological stress, as seen in studies where expressive children were less stressed.

2. Verbalize Thoughts to Reduce Anxiety

Transform swirling thoughts and feelings into spoken or written words to engage the logical prefrontal cortex and impose a story structure, which reduces uncertainty and anxiety.

3. Validate Feelings, Not Just Advise

When listening to others, prioritize validation by acknowledging their feelings (e.g., “I hear you,” “That sounds hard,” “That sucks”) over offering advice, as it is more comforting and increases well-being.

4. Avoid Undersharing’s Steep Costs

Be aware that undersharing leads to missed opportunities in relationships, work, and life, and can result in rumination, mental load, and lower well-being, as not saying something is an active choice with consequences.

5. Clarify Disclosure Goals

Before revealing, understand your purpose (e.g., venting, seeking support, influencing change) because your goal dictates the appropriate context, timing, and audience for disclosure.

6. Evaluate Disclosure with Four Quadrants

When making disclosure decisions, consider not only the risks and benefits of revealing, but also the costs and benefits of not revealing, to make a more informed and strategic choice (the Ben Franklin upgrade).

7. Go One Layer Deeper in Conversations

To foster true connection beyond small talk, go one level deeper than usual by commenting on the meaning of events to you, rather than just what happened, and then invite the other person to share.

8. Practice “I Feel, I Need” Statements

In conversations, articulate your feelings using an expanded emotional vocabulary, and clearly state your needs (e.g., “I need a hug,” “I need you to listen”) to avoid mind-reading expectations and improve communication.

9. Listen First for Effective Feedback

When delivering difficult feedback, spend the majority of the meeting listening to the other person first to understand their perspective, disarm defensiveness, and make the conversation more developmental.

10. Begin Feedback with Appreciation

When giving constructive feedback, always start with a compliment or expression of appreciation for the employee, as this “first slice” of the feedback sandwich is vitally important for its reception.

11. Refine Emotional Vocabulary

Use tools like an emotions wheel to expand your emotional vocabulary, helping you to better understand and articulate your inner state, which is foundational for effective self-disclosure.

12. Address Mind-Reading Expectations

Recognize and challenge the implicit belief that others should just know how you feel, as this “mind-reading expectation” can undermine relationships by reducing curiosity and communication.

13. Experiment to Build Disclosure Skills

Treat revealing as a skill that improves with practice; experiment by going a little further than you think you should in various situations to develop a better feel for appropriate disclosure.

14. Share Feelings to Prevent Regrets

Share your feelings more often to avoid common life regrets, as studies show that a significant majority of regrets are about things not done, and “I wish I had shared my feelings more” is a top regret of the dying.

The real danger is TLI, too little information.

Trust, it's really the currency of social relationships.

Not saying something is a very active thing, right? We get annoyed, we ruminate, that's annoying, it's bad for our well-being.

Leslie John

A life of undersharing is a life of missed opportunities. It's a life of friendships that never blossom. It's a life of colleagues who never quite trust you. Romances that never spark. Relationships that fade apart instead of deepening.

What feels like over-communicating, it turns out is mostly just communicating.

80% of the time it was reciprocated, which I think we can take a lot of comfort in, right? Like I would have guessed, like my catastrophic thinker, I would have guessed it's way lower if I say I love you, right? That it would be reciprocated.

Navigating Difficult Conversations or Giving Constructive Feedback

Leslie John
  1. Spend the majority of the meeting listening to the other person's perspective to understand them better and allow them to feel heard.
  2. Start with a genuine positive statement or expression of appreciation, as this 'first slice' of the feedback sandwich is vitally important.
  3. Use 'I feel' statements to articulate your emotions, ensuring you are expressing actual feelings rather than cognitions or thoughts.
  4. Use 'I need' statements to clearly communicate your specific requirements, as others cannot read your mind and often have 'mind reading expectations'.
