We know that severe stress (such as trauma) leaves chemical marks on the genes, potentially passed down to the offspring. For example, this paper writes about an “accumulating amount of evidence of an enduring effect of trauma exposure to be passed to offspring transgenerationally: https://pmc.ncbi.nlm.nih.gov/articles/PMC5977074/

Though “lived experience” can encompass a lot of things, it definitely encompasses severe stress.

For example, constantly worrying about money because you’re poor can definitely put you under severe stress. Also, growing up without secure attachment to your caretakers, being asked to do role reversal (having to take care of your parents as a child), things like that will generate complex PTSD.

The comment you’re replying to suggests “lived experience” is too broad, not too narrow. The issue isn’t that it fails to include your example. It fails to exclude other things. Part of my lived experience today was seeing a manatee. It is unlikely this will be passed on.

		It feels so wonderfully weird reading about some else seeing a manatee today. I too saw a manatee while walking with my kids today. The interesting part was our navigational strategies complementing each other (me – misremembering the details of a road closure, and them - getting curious about what a bunch of people at a marina are looking at) to find a group of manatees in a place we didn’t know they can be found.

		And the comment you’re replying to suggests that since many lived experiences are plausibly heritable, the term is appropriate. In any case, the context in which it is actually used in the article seems beyond all but the most pedantic reproach: >The first is how a father’s body physically encodes lived experience, such as stress, diet, exercise or nicotine use And that’s a single sentence partway through the article. From the beginning, the refrain is the list of the sorts of things that seem to have heritable effect, not the phrase “lived experiences”. >Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children >Within a sperm’s minuscule head are stowaway molecules, which enter the egg and convey information about the father’s fitness, such as diet, exercise habits and stress levels, to his offspring Etc. The article is clearly not attempting to suggest that all experiences are heritable.

A lot of this is transmitted via the language. The stories we form as a result of events in our lives, have power to set our values in all areas. These myths of the self, have what is essentially a value manifest for someone. And these myths, can be so strongly held that it will influence the person and family’s moods, actions, habits.

What is important is to note that there are many formulas for consciousness. Some are truely bonkers, some are just fundamental truth. And some… have yet to be discovered.

Permutations and combinatorics create a hyperspace of all ridiculous things!

> The authors pointed out “there are significant drawbacks in the existing human literature” including “lack of longitudinal studies, methodological heterogeneity, selection of tissue type, and the influence of developmental stage and trauma type on methylation outcomes”

The literature in this area is a mess, has become highly politicized. I’d give it another 10 or so years before I made any strong statements about these effects in humans. Famously the study of Holocaust survivors’ descendants didn’t show transgenerational effects.
