Dear Dr. Sundali, Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process. Please submit your revised manuscript by Dec 20 2025 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org . When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.
If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter. If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols . Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols . We look forward to receiving your revised manuscript. Kind regards, Alexander Zimper Academic Editor PLOS ONE Journal Requirements: When submitting your revision, we need you to address these additional requirements. 1.Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. The PLOS ONE style templates can be found at https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and 2. When completing the data availability statement of the submission form, you indicated that you will make your data available on acceptance. We strongly recommend all authors decide on a data sharing plan before acceptance, as the process can be lengthy and hold up publication timelines. Please note that, though access restrictions are acceptable now, your entire data will need to be made freely accessible if your manuscript is accepted for publication. This policy applies to all data except where public deposition would breach compliance with the protocol approved by your research ethics board. If you are unable to adhere to our open data policy, please kindly revise your statement to explain your reasoning and we will seek the editor's input on an exemption. Please be assured that, once you have provided your new statement, the assessment of your exemption will not hold up the peer review process. 3. Please include your full ethics statement in the ‘Methods’ section of your manuscript file. In your statement, please include the full name of the IRB or ethics committee who approved or waived your study, as well as whether or not you obtained informed written or verbal consent. If consent was waived for your study, please include this information in your statement as well. 4. Please include captions for your Supporting Information files at the end of your manuscript, and update any in-text citations to match accordingly. Please see our Supporting Information guidelines for more information: http://journals.plos.org/plosone/s/supporting-information . 5. We note that there is identifying data in the Supporting Information file < Appendix.docx>. Due to the inclusion of these potentially identifying data, we have removed this file from your file inventory. Prior to sharing human research participant data, authors should consult with an ethics committee to ensure data are shared in accordance with participant consent and all applicable local laws. Data sharing should never compromise participant privacy. It is therefore not appropriate to publicly share personally identifiable data on human research participants. The following are examples of data that should not be shared: -Name, initials, physical address -Ages more specific than whole numbers -Internet protocol (IP) address -Specific dates (birth dates, death dates, examination dates, etc.) -Contact information such as phone number or email address -Location data -ID numbers that seem specific (long numbers, include initials, titled “Hospital ID”) rather than random (small numbers in numerical order) Data that are not directly identifying may also be inappropriate to share, as in combination they can become identifying. For example, data collected from a small group of participants, vulnerable populations, or private groups should not be shared if they involve indirect identifiers (such as sex, ethnicity, location, etc.) that may risk the identification of study participants. Additional guidance on preparing raw data for publication can be found in our Data Policy (https://journals.plos.org/plosone/s/data-availability#loc-human-research-participant-data-and-other-sensitive-data) and in the following article: http://www.bmj.com/content/340/bmj.c181.long. Please remove or anonymize all personal information (<specific identifying information in file to be removed>), ensure that the data shared are in accordance with participant consent, and re-upload a fully anonymized data set. Please note that spreadsheet columns with personal information must be removed and not hidden as all hidden columns will appear in the published file. 6. If the reviewer comments include a recommendation to cite specific previously published works, please review and evaluate these publications to determine whether they are relevant and should be cited. There is no requirement to cite these works unless the editor has indicated otherwise. Additional Editor Comments: Dear Authors, I have now received two reports. Reviewer 1 is rather positive and makes mainly editorial suggestions. Reviewer 2 is quite negative and provides many detailed critique points. His/her main concerns are (i) that you are too imprecise in arriving at conclusions from your experiment and (ii) that you are overselling some of your results. Both reviewers agree that your findings are not surprising. Although Reviewer 2 recommends rejection, he/she writes to me: "If you decide to help the authors to publish this paper, there will be a substantial revision, rewriting many sessions and tone down the story of intergeneration advice. They can talk about social influence instead." I am willing to give you the opportunity to substantially revise the paper in order to make it more precise and toned-down. Good luck, Alex [Note: HTML markup is below. Please do not edit.] Reviewer's Responses to Questions Comments to the Author 1. Is the manuscript technically sound, and do the data support the conclusions? Reviewer #1: Partly Reviewer #2: No ********** 2. Has the statistical analysis been performed appropriately and rigorously? -->?> Reviewer #1: Yes Reviewer #2: Yes ********** 3. Have the authors made all data underlying the findings in their manuscript fully available??> The PLOS Data policy Reviewer #1: Yes Reviewer #2: No ********** 4. Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: Yes Reviewer #2: No ********** Reviewer #1: The contribution is incremental and effectively highlights the effects of counseling. While well-conducted, the findings may not significantly alter the views of those familiar with social learning theory, as they may be seen as extensions of existing ideas. Here are some recommendations: 1) The experimental design is clear and valid; however, causality claims should be made cautiously, as real-world connections require more justification. 2) Framing the treatment as "parental advice" may lead to conformity with social norms rather than genuine belief changes; more precise distinctions between "beliefs" and "risk aversion" are needed. 3) Overall, the writing is engaging, but the term "significant impact" could be clarified; distinguishing between economic and statistical significance is important. 4) Consider reviewing the formatting of figures that resemble spreadsheet tables. 5) Adding a conclusions section is suggested, though optional. These comments may benefit this research. Reviewer #2: The paper studies whether “intergenerational” investment advice, messages framed as coming from a prior cohort (framed as “parents”/“grandparents”), affects subsequent cohorts’ portfolio choices and beliefs in a 30‑period asset‑allocation task. In Experiment 1, Generation 2 (G2) is randomly assigned to receive either positive or negative advice written by investors in Generation 1 (G1). All G2 subjects then face the same return stream (S&P 500 price returns from 1951–1980 in randomized order, though I have a question about this, see below), allocate between a safe asset and a risky asset each period, and provide point forecasts of the next risky return. Experiment 2 gives Generation 3 (G3) two pieces of advice (from G1 and G2), yielding four conditions thanks to the mixture of experiences: Pos/Pos, Pos/Neg, Neg/Pos, Neg/Neg. The authors find that advice valence moves average risky shares materially (e.g., in G2 about 49% vs. 30% risky; in G3 about 59% in Pos/Pos vs. 34% in Neg/Neg), with differences present from the first decision and persistent over 30 periods (see Figs. 6, 8, 9; Tables 4, 6). The paper also explores mechanisms using mediation analyses, concluding that advice mainly shifts beliefs in G2 but (tentatively) risk aversion in G3. While the results look quite clear, I have some serious reservations about the quality of the paper. At its current state, it is not recommended to publish it. Major comments 1. The core claim of “intergenerational” effects is not supported by the design. Advice comes from anonymous prior lab cohorts that are merely framed as “parents/grandparents,” not from actual parent–child links or documented family transmission. The welfare of their “children” is not explicitly in their utility function (maybe they do, but you lose control over how different people treat their children’s welfare). This is similar to social influence, not intergenerational transmission. Thus, the interpretation seems to be too much of a stretch. I would stick to a social influence story, from one cohort to the next, and certainly not sell it as an inter-generational story. 2. The mechanism claims are not credible. “Risk aversion” is proxied by a single item: “How risky is Asset B to you? (1 --- 5)”, which is risk perception, not preference. Mediation analyses then label this as a preference channel. If you measured it separately, then I must have completely missed it. 3. How exactly people were affected by the previous cohort’s message is also not entirely clear. There are pre-scripted messages but there are also free-formed messages, which carries more weight is unclear. “positive” vs. “negative” snippets differ in content, directive strength, and length and are bundled with a strong authority cue (“parents/grandparents”). The design cannot identify whether effects come from advice valence, directive content, or source credibility. 4. It is entirely unclear how you incentivize your subjects. Should we be concerned about hedging due to the payment of both belief elicitation and investment? Please clarify the payoff is calculated from portfolio outcomes to money. The text states a $5 show up fee plus “earnings in the investment task,” but the conversion for allocation payoffs is not spelled out in the main text. If allocation payoffs were small or hypothetical, demand effects from advice become a more plausible driver. Please provide more lab details. How much do your subjects earn on average? 5. You should discuss your hypotheses section more seriously, not just loosely saying that these were derived from the literature. How? It is clear to the reader. 6. Random or not? You said the returns are drawn randomly, but then you also wrote that it was your design choice to have a crash in the end to create a salient effect. Are you deceiving your subjects in the instructions, or am I missing something? 7. Presentation is not at a publishable standard: You should write the experimental design section properly, instead of copying context from the instructions with bullet points. Other minor issues include inconsistent currency symbols (€ vs $, I thought the experiment was in the US?), many typos (e.g., “Kahnneman”, “advicd”), inconsistent safe asset return, etc. ********** what does this mean? ). If published, this will include your full peer review and any attached files. If you choose “no”, your identity will remain anonymous but your review may still be made public.
